Dream Marks On My Pillow

When I lay in bed at night and cannot sleep, i think. I think about things I have to do the next day or the following days. I often stress myself out, making it even harder to sleep.
Somtimes I will make up "what ifs" in my head, such as what would happen if someone broke into my house and what would be my plan.
Other times I may try to get on my phone and occupy my mind. Usually that wakes me up more than it puts me to sleep. I have a hard time keeping myself asleep. By mind begs for sleep  but  my body refuses. I am a very picky sleeper. It must be pitch dark and silent. My mind looks for reasons to stay awake. The bed must also be a certain temperature. I prefer for my bed and pillow to be cool but my covers to be warm. When one side of the bed becomes too warm, i will rotate to the other side. I fight sleep until my eyelids become to heavy to stay open and my body becomes weak and restless. It is then that I finally find myself falling asleep.
