10 Horror Movie Nightmares WITHIN Nightmares

10. Jen's Cave Nightmare - Revenge (2017)

Revenge does exactly what it says on the tin - this is Mad Max meets I Spit On Your Grave, and is not for the easily shocked. In fact, the opening act is so uncomfortable to watch, it almost strays into a different genre altogether.

Jen is invited to her rich boyfriend's weekend hunting getaway in a remote luxury home overlooking an expanse of desert. When Richard leaves on an errand, his friend Stan viciously sexually assaults Jen, as Dimitri does nothing to intervene. Richard returns to the scene and instead of doing the right thing, he tries to persuade Jen to forget the whole incident. She flees but Richard pursues her, pushing Jen from a cliff and impaling her on the limb of a dead tree. Amazingly, she survives.

She finds refuge in a cave and using some peyote as anaesthetic, cauterises her wounds. She wakes and prepares to leave the cave when Richard suddenly appears and blows her head off with a shotgun, forcing her awake from a drug induced nightmare. She leaves again, Richard shows up with the shotgun, and bang, another nightmare. As she continues to dream, this time it's trippy; lizards, flashbacks, revenge fantasies and once again, she wakes in the cave. That's two fake outs in a row.

By the time she finally leaves the cave for real, the scene is set for her vengeance and you're with her the whole way - Jen deserves every drop of blood she squeezes from these three scumbags.
