Weird Dream...

I just woke up from a very good sleep and I just had a really strange dream... It was a peaceful day and I was hanging out with my friends. There were four of us, though I couldn't make out who among my friends am I with. Then something happened and there were people running after us. Then the environment changed as well into something like post apocalyptic. We ran for our lives but one of my friends went the other way and couldn't catch up with us. We hid ourselves into some hidden inn of some kind where other people are also hiding. When we were in our room we argued about what to do next to escape and then poof I woke up... weird...
