Never bring your work home with you -- especially if your job involves ghost-hunting and human skulls -- because you could end up with one pissed-off spirit haunting your house ... and pushing your friends down stairs.
"Ghost Adventures" star Zak Bagans tells TMZ, the supernatural encounters began after he found a human skull during an investigation last month at an old mining town hotel -- and genius actually decided to bring the remains home with him.
Zak -- who built a display for the skull in the basement of his Las Vegas home -- tells us, he noticed a huge surge in paranormal activity almost instantly ... an angry, demonic-type presence that had never been in his house before.
On one night, Zak tells us, he was woken up by a slight pressure on his ankles -- what felt like hands grabbing him -- and all of a sudden, the force yanked him several inches down in his bed.
Days later, Zak says he had a girl over at his house -- and out of nowhere, she spilled head over heels down his stairs ... insisting someone ... or something ... had pushed her.
But that's just the tip of the iceberg -- and Zak tells us, he's so terrified ... he hired a local bishop to perform an exorcism at his house in the next two weeks
Zak adds, "I love my job, but i want to feel safe in my house. I don't feel safe." Word to the wise -- don't jack human skulls and bring them into your house.
'Ghost' Investigators -- Cast Away from 'Idol' Mansion
4/5/2011 6:30 AM PDT BY TMZ STAFF
The "Ghost Adventures" crew will NOT be allowed to investigate the "American Idol" mansion for paranormal activity -- because TMZ has learned, the owner is worried about their negative energy.
As we previously reported, the ghost seekers contacted people at "Idol" to investigate the mansion ... after the contestants living there claimed the place was haunted -- but we're told, the owner of the house quickly shut down the whole operation.
Zak Bagans -- lead paranormal investigator -- tells us, the owner was worried about all the ghost-infestation publicity ... and wanted to ward off any more possibly negative attention.
Bottom line -- the "Ghost Adventures" crew won't be exorcising "Idol" demons any time soon. Boo-hoo.
