I've only recently noticed that when I dream, I often forget how to move my legs. I have trouble walking (almost as if I'm paralyzed). The problem is, I've been trying to use this to my advantage when asleep, but can never seem to 'remember' this sign. I know that the logic portion of my brain is shut off during dreaming. Is this why I can't remember that this is a dream sign? And what can I do to make myself remember?
