I've only had two of those dreams before and the last one was 6 months to a year or more ago, thankfully :-)

Dreary but not depressing. It was more like I didn't "exist" but was just part of the scene. But it wasn't a "waiting" either because there was nothing there to wait for. That's what was so anxiety producing; the feeling in those dreams was more anxiety that nothing was going to change.

But I was struggling in last night's dream, trying to wake up but being too "sick" and trying to fight the depression like it was a "problem". I've been reading weird science fiction books. They have "destroyers" and "devourers" and the good guys are fighting against them; maybe that's where it all came from. That and my actually going to the doctor's yesterday and normally I have to "fight" him and feel like I have to convince him of my way of thinking about certain medical conditions/meds, etc. My asthma, when it's being a problem gets worse at night too and I think that was all mixed in there as I had to get up a couple times to use my inhaler on the way to/from the bathroom, etc. I think I was just a mess last night and echoed it in my dream :-) But I'd never literally dreamed I was depressed or had that be the "focus" of a dream like last night.
