Sleepless nights

Silent night, holy night , All is calm all is bright...... I guess everyone is familiar with this song. Everytime when i can't sleep or when the night is silent this song will automatically appear in my mind. The more it keeps singing in my mind makes me feel that the night is so quiet and I'm so alone. At the mean time , I will think of the past, think of my family. The only time I will have sleepless night is when I'm new to an environment. I will feel insecure which makes me keep awaking the whole night. I still remember the first day of moving in to UT ( a place where I stay ) , I hardly slept that night. Not only that night, but a few nights. This was because i'm new to the bedroom and my roommate is not there. I kept imagine of all the unseen things ( huh, having watching too much scary movies and this is the result. haha... ) . My roommate came back on the third day. By then, I slept well. Another time I have sleepless night was when I'm still a child ( maybe 7 or 8 yrs old ). That time was because I slept too much in the evening. Hehe... That's why I don't take nap. Sleepless nights are so painful. You're tired but you just can't seems to fall asleep. No matter how hard you try to sleep but it just doesn't work. The night seems so long. You just can't wait for the morning to come.
