Hallucination?

I'm not sure what led up to it, but I had one of those very strange, oddly detailed dreams last night.

I was in a room full of chiropractors, as though I had stumbled into a convention of some sort.

I made some smart-ass comment to the effect that their entire profession was bogus and that there was no clinical evidence of the efficacy of their work. (You know, as I'm so prone to do.)

Then I was in a room full of angry chiropractors.

To complete all the strangeness, though, was that my first thought upon waking up was wondering why I'm only so unfailingly articulate when I'm mouthing off to a room full of strangers in my sleep...
