I dunno what this is but...

This has only happened like 3 or 4 times to me, while I'm almost asleep lying in bed... I'll be trying to go to sleep, when BAM! I feels like something has hit me, but Its like I don't feel any pain or anything.. its sorta hard to discribe, and when It happens I'm mostly awake... and that wakes me up anymore. I happened a few days ago, but for some reason this one felt like it was a gunshot, I don't know how I knew It was a gunshot, I just did... I really don't know if I was dreaming or not, I don't think so because I kinda... felt it. So like... is this just me imagining things, or what?

This is an FAQ (see <http://www.dreamviews.com/community/showthread.php?t=36257&highlight=hypnic+jerk>). Called a "hypnic jerk". Wikipedia says its "completely normal, and are experienced by most people, especially when over-tired or sleeping uncomfortably". "feelings associated with relaxation before sleep are misinterpreted by the brain as falling or toppling over, and by reflex the body jerks out the limbs to stay upright". Sounds like a good explanation to me.

yeah it happens to me sometimes. I remember one time in my dream I was hit with a spear (don't ask me why) and my arm actually flew back in real life. Heh heh.
