Brainstorm 6

This is my favorite/best idea I think. The inspiration started, yet again, with a dream I had a while ago...

A man in his late 20's lives alone and starts to develop terrible nightmares. Each nightmare is different, but he always ends up killing someone for one reason or another. He wakes up terrified each morning only to find that he actually has not escaped them. These are not nightmares he is having, but sleepwalking episodes. He has been murdering people in his sleep. The nightmares do not correlate exactly with the murders. In other words, what happens in his nightmares is not what is playing out in real life, but he is sleepwalking and encountering real, unfortunate people that he ultimately kills.

His fear of being locked up either in prison or a mental institution prevent him from confessing to anyone. Instead he creates an unmarked graveyard in the backyard. He seeks professional help and looks up tips on how to stop sleepwalking and prevent nightmares. Nothing works. Locking himself up at night doesn't work and he has nobody to lock him up.

As a last resort, he tries to prevent himself from sleeping at all. The effects of the lack of sleep eventually get so bad that he has horrible hallucinations. These hallucinations eventually lead to his last murder, which happens to be a lot less discrete than his others and he gets caught. He then becomes what he tried so hard to avoid--a mental patient.
