4.00 A.M !!

It's 4 a.m now and I just woke up.. It's very silent.. Since the sem break begun till now, I felt like having sort of sleeping disorder.. Sighed.. My bed time is not fixed, I can sleep at 12 p.m, 2 p.m, 8 p.m, or whatever time.. I also can don't sleep the whole day.. Furthermore, I also have various sleeping hours, sometimes I slept for 6 hours, sometimes more than 10 and sometimes 2..... This kind of abnormal sleeping habit made me felt dreadful... For example like now, yesterday I slept at 9 p.m and I woke at 4 a.m... I felt very boring, nothing to do when you woke up so early in the morning... I bet almost all of my friends are having their sweat dreams, it's just a lonely and deadly night... Abnormal....
