The bus obviously symbolises that you need to make a transition in your life. A red bus means that you should quit your job, a green bus means that you should buy a farm.

A camp symbolises a fight of some kind. Tents mean fights with old fashioned weapons, a hotel means a war with nuclear warheads.

The dream is clearly a sign that you will be killed if you don't make the right lifestyle change. I hope you can remember what colour that bus was.
