The "Idol" gang FREAKED OUT when a series of crazy "coincidences" occurred in the Bev Hills mansion back in March ... including a spooky spider infestation, flickering lights and one of the wannabes SWORE they saw a white sheet come to life and float down the stairs.
But now, the house has officially sold to a guy named Steven B. Dunn -- the guy who started a baby product company called Munchkin, Inc. ... which posted more than $100 mil in sales in 2008.
The house -- 9 beds, 9 baths, giant pool, marble all over the place and a motor court with enough room to park 100 cars -- was originally on the market for $12 mil ... so it appears Dunn got himself quite a deal.
Ya know ... except for the GHOSTS!!!!!!!
