Now I know why I don't like horror movies about Evil, in the modern genre: a percentage of my nightmares remind me of those movies.
On the flip side... they make truly scary material for stories, etc. for the really scary moments when a smart, insidious evil is after the character(s)---if you can manage to wake up and then to think about WRITING IT ALL DOWN, after you wake.
At least I can get *some* good out of those kinds of nightmares.
Argh---and I was sleeping so good...:(
