Can you do reality checks every time that you wake up? This will help you become lucid during all of your false awakenings, and try to turn the inability to move in bed into a dreamsign. Try to remember that in a dream, you don't really have a body, there's no bed or gravity, so you should be able to move since there's no reason for you not to be able to move. Does that make sense? This is a very important concept in dream control, once you've mastered thinking this way controlling your dreams should become significantly easier.
