re: What do you think about when you try to fall asleep?

Sometimes my brain is too preoccupied by a difficult day or apprehension of the next for sleep. I stop the anxious inner chatter by imagining being shipwrecked on a beautiful island abundant with fruit and game. Everything I need for building the treehouse, food/water storage, etc is available on the ship. Somehow this helps me relax and drift into sleep. I make no plans for escaping the island because it is so peaceful that there is no reason to leave.

I have done this ever since I was a little kid. As I got older, I even began including my family and eventually our family friends in the scenario to prevent inbreeding.
