10 Most Terrifying Vacation Horror Movies

One way to put a downer on any vacation, is to undergo a series of hallucinations that have you questioning your own sanity.

For Susannah York's children's author Cathryn, that's exactly the case in 1972's Images. Directed by the legendary Robert Altman, Images sees Cathryn start to see things that aren't there - notably other men in place of her actual husband Hugh (René Auberjonois).

Deciding to swap their London life for a jaunt away to a remote Irish cottage, the picture soon unravels into a tale of obsession, of paranoia and of psychological torment, as Cathryn becomes completely unable to decipher who really is who and what really has or has not happened - all as dead bodies pile up around her.

To Cathryn, her husband takes on the visage of several of her former lovers, while she also starts to be stalked by her own doppelganger. And as Images comes to a close, York's character hits said doppelganger with her car, knocking her off a cliff and killing her.

The kicker is, the final scene of the movie has this doppelganger confront Cathryn, revealing that it was actually hubby Hugh who had been hit and killed.

To say Images is a trippy, trippy picture would be a major understatement. Even the trailer and its score thoroughly messes with your head - as you can see below.
