Hey, lets see if anyone can answer this one, i feel an experiment coming on.

Proprioception is the sense (not one of the 5 human senses) that tells us where our body parts are positioned without having to see them or feel them. It is a sense in that balance is a sense.

So.

Are our proprioception senses active inside dreams?

For instance, suppose you became lucid. Stop and concentrate on where your limbs are. Ignore your dream form, imagine yourself as a ball of dust or whatever, then try and locate where your real life limbs are positioned. Then wake up and see if your position is as you imagined.

My theory is yes. Because when some people sleepwalk, there must be a primitive and subconscious sense of proprioception required to walk or co-ordinate even the basic of actions (example if you tried to walk but your legs happened to be in the wrong position for walking, you would sense this)

pretty complex eh?
