Have you ever seen a ghost or had a paranormal experience?

i've had loads of experiences. my mum and dads house has a few things happen every so often. i've been locked out of the bathroom when no one else was upstairs, it can only be locked from the inside. my dad had to break the lock. the door in their living room was taken off but that is a really long story. it was very strange and my mum didn't want to come home from work. lol.
the place i used to work in was haunted and i saw things a few times like people going into the back room and i followed but there was no one there and no way of getting out without me seeing them.
the light in the bathroom of a flat i lived in kept being turned on and off.
i was in the bath in this house i'm living in now and the toilet flushed. i saw it with my own eyes and i've been alone in here and i've been to the loo and put the seat down and i've gone back up a couple of hours later and the toilet seat has been up.
all i can say is that i must be very open to this stuff.

not seen one personally but I've been hearing a bit about the spirits at work, seen by various staff members, sometimes before they've heard the stories, books falling off shelves, when no-one is near, and not in a draft......
didn't think much of it until now, there has got to be something.

Never seen one and dont want to. I know a few people who say they have though.
