St. Louis (KSDK) -- Should you be scared of Ouija boards? It depends on who you ask, but if you have seen the movie "The Exorcist," the answer is yes.

In the popular scary movie, the character Regan uses the Ouija board with her mom.

The producers had good reason to put the scene in the movie. The movie is based on an actual exorcism performed by priests at Saint Louis University in 1949.

In real life, like the movie, a child was fascinated by the Ouija board. That led to the nighmarish ordeal, where many believe he was possessed by the devil.

It may sound like hocus pocus, so we asked some clergymen.

"I think Ouija boards are dangerous, not because they have power, but because I think they can be channels for things that we do not understand," said Fr. Michael Doody. "A crucifix used in prayer can be a channel for God's grace. It can open us to the reality of the perfect goodness of God. A Ouija board, like other dark totems, I believe can open us to the spirit of evil."

Many skeptics believe being fearful of the Ouija board is laughable, pointing out the board was made by Parker Brothers, so how scary can it be.
