Aday, 65, believes his body acts as a ghost doorway and claims to have spoken to his dead mother and grandmother, reported Sun Online.
"Robbie should absolutely come ghost-hunting with me. There are so many places to go. We could head to the old A&M recording studios in LA. They think Charlie Chaplin's down there.
"There are people they say are conduits, who are more open to it, and so this stuff's been going on since I was a kid. I've seen my mother after she died and my grandmother. I talked to my mother, and she talked back," Loaf said.
