Billy Joel said the song "River of Dreams" came to him in the night. However, he wasn't imagining things on a separate occasion at his former home in East Hampton, New York.
In an interview with Details magazine, Joel admits to having seen an apparition. "...I walked into my bedroom and I saw what looked like a woman brushing her hair in front of a mirror. She was very old-fashioned-looking—it looked like a 19th-century woman in a dressing gown. It was quite realistic. It was quite three-dimensional. I wasn’t dreaming. I saw this. It lasted for about a minute," said the singer.
While the artist is a self-confessed atheist, he admits that as he grows older, there are more things he cannot explain about the supernatural aspect of the world.
The house was sold to comedian Jerry Seinfeld in 2000. If he has had a similar experience, he hasn't bothered to mention it.
