Any time I ask someone if they've seen the movie
Dreamscape, all I get back is a blank stare. So, for the uninitiated, it's a fantasy movie from 1984 starring
Dennis Quaid. The basic premise is that there exists people with psychic abilities who can, with the aid of some technology, enter into the dreams of other people and interact with them. Alex Gardner (Quaid) is one of these and he is recruited by
Doctor Paul Novotny to... well, here's where my memory's a little fuzzy.
I'll be honest, it's not a great movie, so I've no real incentive to go watch it again. In any event, it turns out that another of the dream explorer psychic guys,
Tommy Ray Glatman (yes, really), is acting as an assassin - entering people's dreams and killing them. The movie proposes that if you die in your dreams, you die in real life. Kind of an overused, empirically-disproven premise, but given the movie's plot it could hardly have gone anywhere interesting without it.

Meanwhile, the President is being plagued by bad dreams of his own. He seeks the help (I think) of whatever organization they all work for and it's then that Tommy Ray is hired to kill the President. There's a big snakeman (see right) which is really more dumb than scary, and Alex wins in the end. No surprise there.
So why talk about it at all? Ah, to share a childhood trauma. See, one of the dreams the President has is of the consequences of a nuclear strike. Specifically, it has him wandering through a post-apocalyptic house while hearing the scariest freaking voices and music ever. He does eventually find the sources of the voices, now mutated by the effects of the blast.
I'd like to say that in retrospect it's kind of stupid and not all that scary, but to heck with that. It's still damn scary! It's not AS bad muted, but, well, just see for yourself:
Thanks to this scene I still - STILL - to this day hesitate sometimes when opening closet doors.
