I don't have escaping dreams, but then most of my dreams in general of some form of frustration, usually not being able to get everything i need to get done before a particular even happens.

My last snake dream was about Lourdes. For some reason, I needed to get him food and he was in a freezer or in like the Artic (why, I have no idea) and I kept getting delayed to get him the food. I remember I was really worried he'd be dead by the time I got him, but in my dream, I got him and put my hand on his side and he turned his head towards as to say "about dang time, woman!"
