Ice Cave

I had a dream last night that I was holed up in an ice cave in Alaska or somewhere with a few people I know through work. We were kind of stranded in the ice cave, but we were making due by burning garbage to keep warm. It started getting too hot, so I went to open the door (huh?) of the ice cave. When I came back to the fire, everyone was in their sleeping bags all, "we're too tired to burn anymore garbage."
