Something really creepy didn't happen to me but it happened to my aunt and I just happened to see her go through it! Well let me tell you the story, one night my aunt and some friends were playing with a ouija board(not a good idea)! Well anyway after that night she started to act really creepy for example she would doze off into some kind of trance, it turned her eyes red and made her think bad thoughts. One time she even went after me with a knife but quickly put it away after seeing my mom walk in the kitchen.
Luckily our great aunt had a boyfriend who was an indian and could tell what was going on just by looking into your eyes. so he did this thing it wasn't quite an exorcism but something similar and thankfully took the bad spirit away but it wasn't all that easy on his part. And i wasn't there to witness the spirit but i could listen from outside and didn't sound like fun!
