After a stressful day, or even a non stressful day, I make headway to just sleep. Often. I tend to make up my mind to sleep for about 20 minutes just as a power nap. But I wake up 2 hours later questioning where I am, whether I'm on earth or not. Most of the time being in regret for wasting my time. So what about power naps? That make us crave it so much? Yes, of course
