Redrobin, I am trying to visualise a fetal position with your back facing the ceiling and I cannot. I thought the fetal position involved by definition lying on one's side.
Asperger96, I am surprised you ever get any sleep at all. Personally, my list is:
If there is background noise, I can't sleep.
If it's too light, I can't sleep.
If my brain is busy thinking, I can't sleep.
If I am very sad, I can't sleep.
If I am very excited, I can't sleep.
If I am too cold or too hot, I can't sleep.
If I am uncomfortable (i.e. something is digging into me), I can't sleep.
If my dog is not curled up next to me, I can't sleep.
If my stuffed toy is not tucked under my arm, I can't sleep.
I suppose a lot of those things are true for everyone but the problem is that my brain is almost always busy thinking. I often lie awake all night long and cannot make myself go to sleep because my brain won't stop thinking.
I keep the TV on low for the noise. Its not loud, but it drowns out other sounds. I can sleep if its that one quiet noise, but not if I can hear all the other noises: Crickets chirping, motorcycles going by, dogs barking, etc
