If you're a big fan of horror movies then, please, read on. If you can't think of anything worse then just turn off your device, go hide under the duvet and never EVER come out.
The latest trailer for Slender Man has been released and if the movie is as terrifying as the two-minute clip suggests then audiences will be leaving cinemas in hysterics.
The movie is based on the online phenomenon of the unnaturally tall man with a featureless head and face, who loves nothing more than terrorising children. The story, influenced by the writings of horror novelist H.P Lovecraft, has allegedly led to a number of violent incidents in the United States.
The trailer can be viewed below, if you dare...
Slender Man will be creeping into Irish cinemas on August 24.
