In some dreams we are suddenly weak and unable to fight off an opponent, or too weak to run. This represents fears of not being able to deal with the situations that face you, or the urges or emotions that arise from within you. It might also mean you feel too weak to say no to someone; or your resolves are weakening. Keeping this in view, why do I have no strength in my dreams?
When we are in REM sleep (where dreaming takes place) our brain turns off all motor functions. This state is called nonreciprocal flaccid paralysis. This is useful to us so that we can be motionless while we sleep and dream, and not "act out" our dreams.
Similarly, why can't I run properly in my dreams? To dream that you are trying to run but cannot make your feet move as fast as you want them to, signifies lack of self-esteem and self-confidence. It may also reflect your actual state of REM paralysis while in the dream state.
Subsequently, one may also ask, why do I punch so weak in my dreams?
However, your body paralyzes your muscles while you're sleeping to prevent you from actually throwing punches. So your brain is getting the response that you haven't actually thrown a punch, and in your dream you get the sensation that it's "weak".
What are my dreams trying to tell me?
Dreams tell you what you really know about something, what you really feel. They point you toward what you need for growth, integration, expression, and the health of your relationships to person, place and thing. When we talk about our dreams coming true, we're talking about our ambitions.
