The kind of sleep that I am speaking of is the kind that can only be described as the Goldilocks sleep. It is when you go to bed, and wake up refreshed. This sleep is usually only about seven to eight hours long, but when you wake up it is like you were hibernating, and now you are alive again.
Everything seems to be a bit clearer. Your mind seems to be sharp and your body finally feels they way that you want it to. Your day seems to go the exact way that you had hoped that it would, and in general, you feel fantastic.
