Winter war and secret spaces

I just remembered a dream I had some nights ago... It was in the middle of a very loooong winter, and on the field in front of our house there was a building of sorts. I believe it was even underground, like a bunker or something. We (some people I don't remember and myself) were hiding from something in there, and as often happens in my dreams I found a secret door in the back, which lead to a hallway. I went in there by myself, to figure out what was in there - pretty much just more rooms, but hidden within each other like those Russian Matryoshka dolls. I don't remember much more, but suddenly there was a feeling of there being a war outside, and that we actually were in a bunker. The enemy got closer and all of us went through the secret door to hide... There was something about there being wolves outside as well, but I can't remember...

I woke up on my back, which is usually when I have my scariest dreams, but this one was more stressful - kinda exciting, really - rather than scary. This actually kinda common about my war dreams. And I have plenty of those, I just never remember much of them in the morning.

Hmmmmm, I'm sure this is all very deep and profound...
