The strangest thing I've seen in my life.
I still can't explain it until this day but it happened back when I was 17 I believe. It was 2 am, I was laying in my bed and I was very upset for some reason. I was looking outside the window and I noticed only the moon in the sky, no stars. Suddenly I see a black shadow moving really fast between the trees. It wasn't human but it didn't look like an animal either. The black shadow kept circling outside my window, and I start crying hysterically. It was moving too fast for me to see what it was, and I was terrified. I think I cried for 2 hours that night. The shadow dissapeared again, and I finally passed out from fear and tears. I still can't explain it to this day, maybe I was hallucinating. I went into a severe depression after that.
