I'm the same way, except it's for sleeping anywhere other than my bed. Sleeping in public places makes me feel unsafe, and sleeping in beds other than my own makes me uncomfortable for whatever reason.

I drive truck and I'm in the truck five to six days a week. The trucks aren't mine, but when I get a truck I move in and make it comfy for myself. I have pretty severe insomnia and barely sleep as it is in my own bed. I sleep less in my truck, and I don't sleep when I have to sleep in a different truck when my truck breaks down. I don't sleep in hotels either.
