I was awake for over 24 hours before trying to sleep today; i was waiting for the sun to be off of my room. But when i went to bed i had trouble falling asleep even though i felt very sleepy. As i was lying there it seemed as though i wasn't sleeping and just thinking, but when i checked the time 4 hours had passed. I have no idea how much i slept or when sleep initiated. I remember moving around a lot, and thinking, but not dreaming.
