Can anyone give an account of a poltergeist intrusion?

I got freaked Reading about it... I don't believe in the paranormal but I know of someone who experianced the same but instead a pair of legs haunted there home till a gypsy knocked on their door, a gust of wind blew through the house ( windless day) , he the legged and they never saw it again. I think because they were doing the ouiji board thing ( never done it and never ever want to) they saw what they wanted to see, I don't know I guess on these things you have to come up with ur own conclusion
