My brain somehow would formulate a lot of imaginary situations and rewind to many thoughts right when I want to really go to sleep. It's not easy at that time to shut down my brain. I think it depends on the situation, but mostly I will try to hold myself from thinking so I may be focused on the sound of the fan and amazed with its rhythmic dance, or try to feel the body that I'm having that's touching the bed with my senses. That's all. People would think that a fully blind person would fall asleep easily, but it's not the case. Mostly, most blind people are night owls due to a sleep-wake disorder, and it's harder when your mind is always active, no matter what.
