Strange Dream About Mass Suicide

I had a strange dream this morning where I was with a group of people, unknown to me. There was some sort of event coming, like a tsunami that was going to wipe us all out (I live on the West Coast near SF, BTW). The people I was with just decided to "give up" rather than face whatever was coming. We walked over to an old auto yard and these people climbed into a car crusher. There was whole families and they just willingly climbed in. I refused to go in and kept trying to talk them out of killing themselves but all they wanted was for me to press the button on the machine and to join them. They all acted like whatever it was that was coming was worse than killing themselves in a horrible way.

Just thought I'd mention my dream and see if anyone else had something similar or a unique interpretation of it's meaning.
