I can't sleep if I'm too hot. If I'm too hot, I just DON'T sleep. And I HAVE to have my fluffy sheep Lambchop, my beanie toy dog Maude and Horse the zebra, or I get restless and nervous. Also anything less or more than two pillows and I freak out and become convinced my head is too high/slow and get stressed out and can't fall asleep. I'm weird. And I also really cannot sleep anywhere except my own bed in my own house.
