sleep and awake is always happen to you, to me and to everyone in every night and day. tonight, while i was sleeping and dreaming about something that i don’t really remember, suddenly i woke up. don’t know why i woke up. as usual, when i wake up i always have a glass of pure water and then i go to bed again, but tonight i can’t even feel sleepy again. why? I don’t know too but something just happened.
