Can I move my real body in a dream by mistake?

So I recently found my first and second lucid dream via FILD method and as I had never really done anything before in a dream. I didn't want to do much moving so very slowly I closed my hands together and rubbed them in my dream as a first thought. I had the thought of accidentally moving my real body if I attempted to move in my dream. I know the body goes into a paralysis but if I am into a dream really quick is there a chance I might move my real body? I know experience is the best way to find out but I don't want to waste one of these moments until I can have them fairly regularly.

Several things - especially when you've started out on lucid dreaming - can shock your body awake.

You really just have to keep pushing the boundaries - believe that the dream will not fade if you move your dream body at a certain speed. Your body is paralyzed while dreaming - do not worry about it.

Hope this helps!

Are you afraid of moving your physical body while still sleeping or of moving and waking up?
I've sometimes while moving in a lucid dream wondered if I was also moving my physical arms or legs, but so far that has not actually been the case. Even if you did move, it probably wouldn't be very much. I wouldn't worry about it, unless maybe you have a history of sleep walking.

If you're worried you might move and wake up, I'd suggest focusing your attention on your dream body and sensations, and that will help keep you from switching awareness to your physical body.

YES! Very possible! I do it all the time this is a way for me to feel how deep I am in my dream and a way for me to check how much time I have left. If I can not move I know I just started, If I can feel the weight of my body I know I am halfway, but if I can twitch my toes and my fingers I know my time is almost up :D This all happens while I am still LD/DC...You have to be super confident and know with all your might that you will NOT loose your dream and be able to quickly regain full control of your dream if you become unfocused you will loose it.
