What happened?
I've never had an experience, but I don't doubt the existence of ghosts
Ive heard too many detailed stories from serious people to write the idea off
Edit: I visited a holocaust remembrance place when I was like 9. I remember walking down some hall with a few other kids and hearing someone whistling from down another corridor. It got closer as if they were walking. We expected someone to come around the corner but no one ever did. One kid walked over to look down the hallway, and started running. Apparently he didnt see anyone and got spooked lmao
