This is by far the best sleep video I've found on UA-cam! Every little noise wakes me up from my partner snoring to the house settling. I listened to this for the 1st time last night and heard absolutely nothing outside of the waves and thunder. I slept like a baby! Now idk how I feel about being that dead to the world but I'll take my chances! 😂
🤗 That's just perfect Eboni Faulkner. Happy to hear that my recordings keep canceling the noises around you. Wish you a great nights sleep tonight! Happy Relaxing to you and your family, Edy 🤗
ocean thunderstorms specifically are the only thing that helps me focus and write my essays for school. i need a lot of sounds going on directly into my brain and this is the perfect amount of stimulating without being distracting. rain wasn't enough, rain and thunder wasn't enough, but rain, thunder, and waves seem to be perfect.
Stumbled upon this the other night looking for something to help sleep through the night for both me and my daughter and my gosh, we both slept amazing. Subscribing and looking forward to more and thank you, its been 2 nights straight sleeping to this. Just beautiful and so dang helpful. I think most of us in our lives are missing this....NATURE.... Thank you.
Thank you for this!! My 8 year old has a hard time falling asleep for school without melatonin but I don’t want to give it every night. This is the one thing I can put on and he falls right to sleep 3-5 mins tops. Thanks for taking the time to create this. It means a lot. From a tired mom
Try valerian super calm for kids. Much better than melatonin. I have even used it myself whenever I had to fly on an airplane. Melatonin may disrupt your child's growth.
We listen to this for nap time and for bed time Your other videos I have played for my baby since he was 2 days old. My husband showed me rain sounds when we first met and your videos are the best now that our baby is almost 2 every night he falls asleep to this one since you posted it. Thank you so much you dont understand the peace it brings us and the way our baby loves and waits for us to put rain sounds on every night its part of our bedtime routine. I personally find the ocean so calming idk why and my husband loves rain and thunder but the cave just ties it all together like the best gift that anyone can give us. My sons zodiac is a cancer and having water be the element of it just really makes sense how much we appreciate this video. Thanks and even if its AI he doesnt have to know. 💙💙💙
So happy that my ocean rainstorm recordings give you so much joy. Actually it's only been a couple of months since I published my first recording of it and I am overwhelmed by your comment, because it shows me that the recordings are actually the right way to do. Happy Relaxing to you, your husband and little toddler. Edy 🤗
Hello there! I want to truly thank you for your content. This is my favorite video, I watch every night. PLEASE do make more just like this! The safety of the cave with the mighty calm of the sea is incredible. Suffering from so many ailments, this truly brings me peace 🙏💚 You are appreciated!! Thank you!
I keep coming back here. The sound just flows over my tinnitus and also calms my nerves. I just wish I could down load this to my phone. I sometimes are at places with no cell coverage. Rural areas where I go have no cellphone coverage. 😊 Thank you for a great upload!
Thank you very much for your lovely words Michael! With UA-cam Premium you can download the videos for offline use. Or simply check out my 10 hours Spotify, Apple Music, etc. playlists. Happy Relaxing to you, Edy 🤗
Hey guys what’s up I’m back with another loving comment guys y are truly and deeply loved and who doesn’t see that they’re the problem love u guys!☺️☺️☺️
It's because most of the people are waking up then and starting the video at this same position the next night. What we learn is that people don't get enough sleep.
I have a dinosaur pillow case that is extra long. There is a metal shelf that hangs above my bed and extends out 12 inches. Secured to wall with bracket, and the metal stripe goes perpendicular with wall. The pillow case I use as a curtain. It hangs down and around the shelf. This rain sound with small fan hanging down off the underside of the shelf provides a quiet, safe, and protective zone for me to sleep sitting upright. I feel more alert. Thank you for the rain. It makes my mom cave restful at 🌙 night😊😊😊
You're freezing, in a cave. You warp yourself in a damp blanket, feeling miserable. You then focus your mind. Exhale slowly. Your body warms up as you slowly drift into bliss.
@@puresleepingvibes thank you for your comment. I like to invent but not sell. I built 3 of them so one is always charging. Thanks for the storm, helps clear the mind.
Thank you for this great recording! It's definitely been an immense help with the insomnia. I think it's wonderful, Edy, that you continue to make these videos to help others! ❤
So lovely of yours Ramona! I will continue doing here what I do. Going into the woods, to the ocean and in the mountains to find great recordings is what you well get in the years to come. 🤗
@puresleepingvibes I know there are many of us who appreciate the time you spend and the passion you have for keeping your channel updated with new content. I, for one, especially appreciate that you include in your descriptions all about the places where you record these storms. It makes it so easy to imagine being there. Thank you, again, for helping me get much better sleep!
I have been listening to this every night for two weeks straight while trying to find ways to fight the insomnia I all of a sudden have that started shortly after I was diagnosed last year with spinal fluid on my brain. I’m still fighting it but getting better everyday as long as I don’t push myself too hard and set myself back for 3 or 4 days. But this…this recorded sound has been so perfect for me and my active brain. Perfectly timed and laid out so you don’t get startled when you start drifting and feel your self getting heavy. So my results of using this every night for two weeks vs not listening to this…. When I didn’t listen I was getting maybe 2 hrs a night. Maybe 4 if I was lucky but I would have woken every half hr during that 4 hrs. But with listening to this… I now fall asleep way way quicker, I sleep for at least a solid 2 1/2-4 hrs. I get up and stretch, use the restroom, get a nice drink of cold water and then put this back on and am usually able to fall back asleep lightly for another two or three hours. So thank you!!! 🙏
Hi TayAnn, I just read through your lovely comment and how you manage to fight spinal fluid on your brain. I really wish you all the best and that you are soon getting better, so your sleep will improve minute for minute as time goes by. Get well soon! Happy Relaxing to you, Edy 🤗
These sleep vibes are wonderful provided there are no advertisements. Unfortunately, youtube cannot grant us the peace that we deserve. Are these sounds more effective at lower volumes?
The rain is falling on my roof. The wind blows through the sky. The world is sleeping sadly now In tears that we have cried. LOST HER IN THE RAIN (C)2006
I don't understand why some other recordings go to a blacked out screen. I just minimize the video being played, & the screen blacks out all by itself. This storm sounds great, I've played another one of your videos. They're the best I've found over a few years❣ I'm very satisfied❣ Kind regards❣
Hi Tam, a lot of viewers watch through their tvs, oled go full black when the screen is black, so the energy consuption is minimal. Happy Relaxing to you, Edy 🤗
@@puresleepingvibes, Thanks for the insight! I'm from another century & time - the '50s, & not much of a technocrat, so thanks for the insight. That makes sense😏👋 .
I've found the perfect cure for insomnia in 3 easy steps!! No joke! What you do is: 1.Get in bed 2. Close your eyes 3. Go to sleep I swear to god this works for me every single time, anyone know how to file for a patent??
@puresleepingvibes I thankyou, it took years of hard work at times I had to dig deep and make huge sacrifices but the fruits of my labour speak for themselves! I don't want to be too presumptuous but I heard a Nobel is being considered for my discovery but please, don't quote me on that, you didnt hear that from me...let's just wait and let those in charge anounce it!
Sweet heart...from another trauma survivor, please take good care of yourself. PTSD is real but getting help and leaving trauma in the past is also real. If you want it you can't have it. Healing ❤
Did you really record this from a cave, at night? I absolutely LOVE this visual! I feel like I am inside the cave, hidden safe and sound watching the ocean........🫠🥰

The rain sounds here are amazing! If anyone’s interested in more,
ocean thunderstorms specifically are the only thing that helps me focus and write my essays for school. i need a lot of sounds going on directly into my brain and this is the perfect amount of stimulating without being distracting. rain wasn't enough, rain and thunder wasn't enough, but rain, thunder, and waves seem to be perfect.
Happy you can concentrate better with may nature sounds. Happy Relaxing to you pollux! 🤗
Christmas Tomorrow, Merry Christmas from Australia everyone! May God bless you this holiday season and may you find true peace and healing 🤍
This is my favorite sleeping sound. Perfect with the ocean and rain hitting the rocks

Correction record time tonight. Put it on less than 60 seconds ago!! Wow! 🎉❤😂
Very lovely Erika. It's good that you try to avoid melatonin. Happy that it works for your child! Happy Relaxing to you and your family! 🤗

Wow! That’s awesome, Mom!
never give your child melatonin.
This is the best one yet. The best thunder sounds. Just the perfect amount of waves, rain and thunder
Happy you fell that way. I always do my best to give you the best recordings 🤗
Wow this video is amazing! Hope everyone here can sleep well and enjoy the night! 😊😊🌊🌊
This sound in particular helps me fall asleep and relax. It’s one of my favorites 🙂
I'm glad you like it 🤗
finally found one that works for me to help me sleep and as someone who deals with insomnia you have my up most appreciation
Yay, cool you found your match. Wish you man good nights to come! 🤗
Videos a little trippy! Like really being in a small cave in the middle of the ocean!
It’s amazing how the rain can bring so much serenity to my day.

Best ambient video ever.
Thank you very much!
ABSOLUTELY PERFECT RAIN SOUND EVER🎉🎉❤❤❤
Thank you very much!
Peace,Love & Light to all ❤❤❤❤
I love the fact that the most replayed part of the video is right before 6:09:00, nice
It's because most of the people are waking up then and starting the video at this same position the next night. What we learn is that people don't get enough sleep.
Just remember life gets better 😊
Prayer.. tea..nature sounds= Sleep. Ty
Jesus walked on water and helped his apostles through the storm hes still here ready to do the same for you. God bless you. Jesus is Lord
Ok
Amen ❤
The visual looks so real it actually freaks me out
Happy you like it though.
Its really important that the sound is clear. Its hard to do that with rain. Some videos are just a static mess. Anyways thanks for the upload!
Hope you like my recordings 🤗
What a beautiful video, is this even real though omg it’s so beautiful 😻
Thank you so much!! 🤗
I fell asleep to this last night and then an ad blasted me out of a dream 😩😩😩
Sorry to hear that, but the problem is on YT side. I deactivated all mid-roll ads. The issue happens on all long videos across UA-cam.
I love it i can sleep through anything
That's awesome! 🤗

Amazing ! I love this sound. It sounds realistic and not overly computerized
Happy you like it that much! 🤗
This is a great mix of sounds 👌 Thanx.
Happy to hear! 🤗
It's horrifying looking at the screen and listing. So i decided to close my eyes...aa haa...that feels good ❤
In what way is it horrifying?

Thank you for hopefully 3 to 4 hours sleep. My tinnitus is getting so bad. Its hard for my children to understand.
Happy it softens your tinnitus a little bit. Wish you more good 7 hours sleep nights to come. And Happy Relaxing to you and your children! 🤗
Went to 😴 sleep with these sounds and woke up with them. I designed a blue tooth headset that lasts for 4 days.
Wow that is amazing. Hope you will find some buyers for your headset, because I think there are a lot out there who a search for such a device!
