Ghost orb caught on video in my daughters room

This was actually filmed july the 6th of 2018. We had only been in the house for 12 days. At 4 seconds into the video look at the bottom right corner. It goes from the bottom to the top traveling up the right side. I didnt notice this until December when I was going back over old videos. At that time, I was not aware of what was all here. I did say from the first time I walked in the house, back when we were still looking that this house gave me a weird feeling.
