Date from Hell (1998)

You are entering another dementia... One not only of sight and sound but of bad breath, empty gas tanks, wilted roses and romantic dinners at Mickey D's. When she left her house, she opened a portal to a very strange very wrong world. A parallel plane that looked just like hers, but one where reason and logic have become the punchlines to some cruel joke... And where time just crawls...on the other hand, the sex is fucking phenomenal.
