Dude, that's just sleep paralysis. Your house isn't haunted. Sleep paralysis happens to almost everyone. It happens to me at least once a month. It's terrifying yes, but it's nothing supernatural. Your eyes are open, but your brain is still in REM basically. Audio and visual hallucinations from your dreams merge with your real-life surroundings. Read this link:
Since you suffer from sleep paralysis, it probably means you're a light sleeper. If you're really concerned about it, I've noticed it never occurs if I leave a light on for some reason. Also, try to lower your stress and sleep on your side (as opposed to face up).
I undersand sleep paralysis, from an intellectual level. The body paralyses itself when you sleep, you wake up with out that paralysis going away and continue with REM sleep.
Its just that for the last several months its been hitting me more and more . . . I don't like it
But that was a nice link, expecially the section on other cultures.
