Do you have a sleep for a hour in the claasroom? Today I take a nap in the classroom at noon. What a terrible experience ! When I get awake, I have a headache untill the end of the day. moreover, I feel bored about everything all the time and still have a desire for sleeping. in view of physical fitness, why does this phenomenon happen ? And it is my actually feelings. but I do not intend to alarm you.
