so shut your eyes, kiss me goodbye, and sleep...

i keep waking up in the middle of the night. 3:30, 4:15, 5:45...
i don't know why. i do not have vivid dreams that pull me out of my sleep. nothing shifts in my room to scare me awake. i simply wake up. my broken up sleep makes it easier to get up in the morning, but makes me more tired during the day.
i want a normal sleep.
