I get weird fantasies sort of like that. Like living out of my car or walking into a forest and not returning. I don't know where they come from or why it happens. I wish I could give you a why answer.

If it is getting stronger talking to a therapist might be in order. As long as it doesn't get close to overwhelmingly strong, I don't know if it is a huge deal but I tend to be proactive rather than try to put out the fire after the house is gone.

Hope that is helpful.
