The upcoming horror movie "Girl on the Third Floor" starring CM Punk finally has a trailer -- and it's pretty damn scary.

According to the synopsis ... Punk plays a character named Don Koch who tries to renovate a rundown mansion with a sordid history, only to learn the house has other plans.

The former WWE star is credited by his real name in the trailer, Phil Brooks.

Our partners at Collider interviewed the cast of the film, including Punk, following the movie's SXSW premiere back in March. The interview can be FOUND HERE.

"Girl on the Third Floor" hits theaters October 25.
