Sounds serious to me too. I would discuss it with someone versed in the meaning of dreams, psychology and the subconcious, a proper psychologist. Counsellors might not do the trick, their training doesn't include Jungian dream analysis. You definately need your sleep. Start by talking to your family doctor.

I don't know if it helps but I once had an apocalypse dream, but it wasn't scarey. I was in my own city after civilization had been destroyed and what it meant to me was that I was ready to leave my city and seek my own adult life elsewhere.
