Does anybody here know if you are more refreshed when you wake up form a LD 
? I mean, your brain might not be sleeping so deeply as it would i a regular dream. I think I often give up on WILD becuase I think I’ll get exhausted, and don’t get the necessary sleep.
I don’t think REM sleep is the phase that refresh your body. I think deep sleep does. 
REM phase is a high-activity phase for your brain anyway, may you be lucid or not…
