Witchboard III: The Possession (1995)

When his landlord shows unemployed stock broker Brian a Ouija board that he claims can predict which stocks to buy, Brian is understandably skeptical. But when the stock takes off, Brian heads back for another Ouija session. To Brian's surprise, his landlord gives him a ring and then commits suicide by jumping off the balcony.

After the funeral, Brian steals the Ouija board, borrows fifty thousand dollars from a loan shark, and tries to make a killing on the market. Unfortunately he does not have the sixty two thousand five hundred dollars that he needs to pay back within twenty four hours. When the loan shark's goon tries to chop off Brian's finger, blood is spilled on the box housing the Ouija and Brian is the only one who leaves the office alive.

Brian's attempt to destroy the Ouija only succeeds in an accident which stops his heart. His wife Julie calls paramedics who seemingly resuscitate him. However Brian has changed. At first it's little things like his hairstyle. But soon Julie is wondering who this person is, as he hits on her best friend right in front of her. Shortly after this she discovers her husband is actually stuck in the mirror and his body is inhabited by demon who intends to impregnate her. Oh the humanity!
