Couple of questions...

When you fall on your face do you wake up? For me it ranges from a height where I'll get seriously injured or a height where I'll die. I get a rush of adrenaline, hit the ground and wake up. When you try to talk, can you? I can but it feels like my vocal chords don't work properly and I need to try a few times to speak at all and it's quite frustrating Thoughts?

Lucid or non? Nonlucids (since it is in this forum) - Yes, normal for people to wake up after or before getting hit. Not impossible for someone to stay in a dream. I've even died and stayed in a dream. Hit in the face and talking... Can't say I remember anything like this, but can't say it wouldn't happen. Not surprised if it happens often.

When you go to sleep your body produces a muscle relaxant that paralyzes your muscles, to keep you from acting out your dreams in the real world. Hence when you try to speak you can't, or you try to run, but you you can only do so in slow motion. I tried to punch someone in a dream once, but I could get my arm to move fast enough. A rush of adrenalin will wake you up, I did a paper on lucid dreaming, and found that if you get too excited, you will wake up. Your body produces adrenalin that wakes you up. I also read that with practice this will not be an issue.

Usually, for most people, they wake up after feeling some sort of pain, via impact with surface, sharp object etc. I can't think of anytime recently that I woke up after me hitting something, or vice versa.
