I have a total lack of strength in dreams. I can punch someone in a dream, full force, and they wont even flinch, so I hit again and once again nothing happens.

Rather than move slowly when trying to run, I stumble repetedly and end up deciding to crawl, then my arms buckle so I decide to drag myself along, then that turns out to be slower than the stumbling was. It's like when you try to walk normally on an unstable surface and you stumble then stumble again when trying to stand back up.
