well, i was just thinking to myself, if someone is sleeping (say a light sleeper or even heavy) and someone walks into your room you'll here it, someone talking in the room you'll wake up to it.. or in general anyone making noise in a room while your tryin to sleep you wake up...

but this is what i was thinking...why cant you wake up when you SNORE? i mean thats loud, how is it that people dont wake themselves up?

...funny i thought about this several times.

About people waking up to noises i don't know, i mean some people are such heavy sleepers that you could switch on a tv while they sleeping and they wouldn't wake up, at least not immediately. Once i snored and woke up myself up, but then again im a light sleeper, every little noise wakes me up. i think it depends if you are a really heavy sleeper or a light one.

its hard to figure why really

My father is a light sleeper yet snores loud enough for the neighbours to hear it (seriously, no joke). But on a couple of occasions he has woken himself up, thankfully 10 years ago he was diagnosed with sleep apnea and now wears a pump to push air down his throat. It had gotten so bad that he would stop breathing.
I talk and snore (delicately snore, thank you, lol.) I also talk when I do I will wake up. But if someone walks into the room or whatever I will sleep through it all. I dont even wake up when the baby cries in the next room I have to have a baby monitor next to my ear turned up full ball.
