You mean when you are actually awake but can't move your body?
Its actually an energy field thing. When your energy field has moved up above the body, or shrunk into one area, the energy itself is also up above the body (or below) or whatever, so the even though the brain gives the 'move' signal, the muscles are unable to access energy to carry out the command. However, sooner or later, the energy field moves back into the body space, and muscle control is restored. You can read about the energy field and how to balance it etc. here;

To dream that you are unable to speak indicates that you are afraid to say something for fear of being criticized or judged. There may also be a situation in your waking life that has left you speechless. As for not being able to move or stand up, there are two meanings: * To dream that you are unable to move signifies feelings of being trapped. Alternatively, it shows that you are too rigid in your attitudes and decisions. * To dream that you are paralyzed, reflects the current state of your body while you are dreaming. During the REM state of sleep, your body is really immobile and paralyzed. People report that they cannot run or hit, despite how hard they try. Symbolically, dreaming that you are paralyzed means you are feeling helpless or pinned down in some aspects or circumstances of your waking life. You may feel unable to deal with a situation or change anything. Alternatively, the dream suggests that you are feeling emotionally paralyzed. You have difficulties expressing your feelings.
