i see what you mean, but touch is firmly shut off in dreams. I dont know why, but you cannot feel specific touch in your dreams, but excessive touchedness () causes you to wake up.

So, i dont think touch is a factor here. All 5 senses are blocked from your awareness, and can only siphon through on a subconsciouss level. (playing a tape while you sleep can help you learn etc)

Proprioception-the sense that tells you where all your limbs are placed, without it we would have to literally look where we were putting our feet to walk-is something totally unrelated to touch.

And what is with the 'i moved my leg in a dream' thing? It has nothing to do with proprioception. If you somehow concentrated on where your feet were PLACED in a dream (try and make your dream body mirror the placement of your physical body for example) and then woke up, and saw that you were correct, and that you DID know what position your IRL body was in from a dream, then proprioception is indeed active in dreams.

Did that shed any light on this?
