50 years later - visiting grandparents old farmhou

Grandma and Grandpa sold the farm house over 50 years ago, and on a whim, I asked a friend to ride with me to go visit the place. ( she is the loudest one you hear in the background) The owners were very gracious, and were very interested in hearing any history about the place. Upstairs, was a great room in the house. This is where my grandparents kept a lot of beds for visiting grandkids. We spent many summers at the farm, working and helping out with the chores. This farm is also where we had our family reunions. After taking a still frame photo of the great room, I noticed a few orbs.
So I turned on the video recorder, and this is what you see. The current owner of the house was in the background and was a little shocked with what he saw. He also states in the video that he felt when he first moved in that someone put their arms around him and cuddled with him. I had turned the video off, and said that that was probably grandma, and told said out loud for Grandma Lucy to knock it off, and leave him alone. LOL
Just having fun. It didn't feel creepy to me. In fact, I felt overjoyed with the thought that Grandpa and Grandma, and many relatives had come to say hello.
There were so many orbs it looked like a strobe light in a dance hall. I hope it comes out clear enough..
