Weak In My Dreams....

In MY dreams...say im fighting someone or something...

When i go to punch its really slow...Like I am moving in slow motion, and when I hit them, lets jsut say in the face. It has no effect liek i am really weak. Does this MEAN anything or jsut a dream...

There are a lot of times when our abilities in dreams seem tanked. I can remember a few instances in dreams where I've tried to flee some unknown pursuer, but for some reason my legs felt numb and weak, so I kept tripping and falling down.
