I have had lots of experience too... THEY FREAK ME OUT! One was my dads one. When my dad was young he was sleeping in he grandfathers room while his sisters were getting washed. By the way his grandad wad in the grave, you know.He heard footsteps under the bed and really scared and checked there and there was his grandads old shoes lying there.. Creepy..
Once I was at school and I went to the loo by myself [ok laugh] I heard someone come in bacically open the door and walk around the loo. I wanted to see who it was and went outside and no one was there and that was scary because they only went IN not out.
Once I was sliding of my bed for fun and something,something wierd pushed me right of head firrst on the floor
