Rocker Liam Gallagher is wracked with fears that his home is haunted - by the ghost of John Lennon. The Oasis frontman has often cited the former Beatle as an enormous influence on his music and career. Now he claims he is often unable to sleep because he thinks he might be about to be visited by a spirit from "another walk of life." Gallagher says, "I was in Manchester at a mate's house. I turned round and there I was, lying on the bed, and I sort of fell back into my body. There was a presence there and it was him, Lennon."
