He even sleeps with the lights on at the house he shares with long-term love All Saints singer Nicole Appleton, 32, and their six-year-old son Gene.
And the Oasis frontman, 35, who had a hit with Wonderwall, is building up to a chilling Hallowe’en after hearing eerie footsteps late at night.
A source said: “Liam is absolutely convinced there is something sinister in some noises he has been hearing late at night when he, Nicole and Gene are all in bed.
“He lies awake listening with the lights on. And he is adamant he hears footsteps going up and down the stairs.
“It’s been happening for some time now and he sometimes wakes up and feels as though he is being watched by someone from another walk of life. He also feels a cold air pass over him when he hears the sounds of the footsteps – usually between 4 and 5am.
“If he had his way, he’d call in the experts to investigate the sounds further. But Nicole reassures him it’s all ok.”
Liam, who lives in north London, is convinced he was once visited by the ghost of his idol John Lennon.
The Burnage-born star insists the late Beatle appeared to him as an apparition while he was staying at a friend’s house years ago in his home city of Manchester.
But instead of being freaked out about the situation, Liam was in awe of his hero.
He said: “I was in Manchester at a mate’s house having a sleep. I remember getting up and feeling really weird.
“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.”
