Dreams are never bad, they are just our unconscious's way of trying to get us to understand something, to help us out understanding our waking life. All the symbols and actions are our own, since it is our dream so the person dreaming is the best able to "interpret" what the dream might be saying to the dreamer.

Your warehouse group dream reminded me a little of "West Side Story" and those two gangs constantly battling one another. I think West Side Story is just another, more modern take on "Romeo and Juliet". Do you have others in your life you feel are more in control of you and your behavior than you are? Do you feel you are being "forced" to participate in life the way they want you to instead of how you'd like it to be? For example, we all have heard of the stories of fathers, grandfathers, etc. all being doctors or lawyers or some other specialty and the son being expected to be that but wanting something else ("Dead Poets Society"). Do you have anything like that going on in your life where you are being forced to put yourself in the stocks and wear a bag over your own head?

It could even be about who you see/associate with, the wealthy girl/guy in love with the person from the "wrong side" of the tracks, sexual orientation, or any other "disagreement" between what you feel and what others want for you.
