Sleepy

Yesterday, I remembered something that I discovered back when I was in college. I, like many autistic people, take medicine to help me focus. This medicine often makes me unable to sleep so I have to take melatonin. Yesterday, I slept without melatonin. Why? Because I listened to something with rhythm. When I was very young, my parents could only get me to sleep by rocking me, violently. Not painfully, mind you, but with more force than is normally needed. The same principle applies with music that has a nice rhythm to me. I find that a good beat rocks me just like the rocking chair. I actually have a game that this effect on me and I was watching someone play it on Youtube. I wonder if the same applies to other autistic people. I know that autistic people are sensitive in that manner but I don't know if it applies to all. I'll post the music here. The game is called: Rhythm Heaven Fever for the Wii.
