When you go to sleep at night for a full 8 hours, but when you wake up, you feel like you have only had a short nap. Usually when you have to go to sleep by a certain time in order to get up and get ready for school or work. Usually you have a desire to go back to sleep because you are still tired, but do not because you: A. Do not want to get fired from your job or B. Are forced to attend school by the United States government.
