OK I guess I'll tell my weird story...
I've never seen a ghost or anything weird in my life, except for a few times.
One time that I saw something weird was a few days after my grandmother had passed away.
I was about 9-10 years old and I was sleeping in my parent's bed. I woke up in the middle of the night.
There was nothing in the chair when I went to sleep, but when I woke up there was what looked like a person with a white sheet over their whole body sitting in the chair and facing my direction, but with their head bowed down.
Somehow I wasn't scared. It was probably because my parents were right next to me so I wasn't going to freak out. I just went right back to sleep after that. If it was me now I would probably have freaked out.
I'm the most scientific, rational person ever, but I can't explain what happened that night. I fully admit that it could have been just a hallucination, but I made sure that I rubbed my eyes and looked at it again and it was still there.
