I have never experienced a ghost, but I believe my mom did.
First off, my parents house is over a 100 years old and we've lived there since 1983 and never experienced anything, until one day. My mom was about ready to taking her usual afternoon nap. Just as she put her head down, she heard footsteps coming up the stairs. And you can imagine, with a house as old as ours, the stairs are not quiet. (I could never sneak home late :). ) She knew I wasn't due home, so she thought it was my brother. But for some reason, she does not know, she didn't call his name. She just laid there quiet, listening. I guess I should tell you kind of how our house is laid out.
Its 3 stories and there is 2 landings on the stairs until you get to the 2nd floor. And when you get to the 2nd floor, my parents room is right there. And the bed is on the right when you enter the room. So my mom couldn't see who was coming up. So then the footsteps proceed to come up the stairs to the 2nd floor landing. Then turns right, to go down the hallway, and the attic stairs are right there. There is a door to the attic, and I'm sorry, but I can't remember if the door was shut or not. I don't think it was, because I don't recall my mom telling me she heard the door open. So then the footsteps go up into the attic and thats it. She's getting scared, cause she isn't hearing anything else. Well, she was home by herself so she called the police. She thought it was an intruder, she didn't know.
The cops went up into the attic and saw nothing. There are 3 closets up there and impossible to get out up there. I have never felt a presence in the house before so I have no idea what that was. Sorry it was long and I hope it wasn't boring, but I thought I'd share that with you. Thanks!
