When I was 10 years old, me and my family were having a picnic by the water in a lakehouse we rented. It was around 7PM, so my family was cooking barbecue for dinner. I went back inside to get some water, and went upstairs to my room to get my phone. As I looked out my room window, I noticed a black figure standing around 200 feet away from where I was sitting, behind some tall grass. I didn't mind it, so I returned to the picnic. I looked again to the grass and there it was, but it was more blob-like figure with a black glow eminating from it. I told my family and when they looked at where I was pointing, it disappeared.
