Why after dreaming of something e.g. doing exercise you feel tired when you wake up?

i think it is because ur body hasnt gone into a deep sleep and also if u were running for example...you r probably tensing ur muscles in you sleep as if u were running in real life...this is probably while u feel tired when you wake up. i have the same problem i will wake up feeling like i have done a load of exercise and knackered
