I've talked in my sleep since childhood, my mom talked "to" us kids when she would nap during the day, too. I think two of my brothers also talk in their sleep, and my 9 year old son does it too - the other day when we were camping he yelled from his bunk in the middle of the night "OH YEAH, *I* HAVE A MONOPOLY GAME!" I about died from trying to keep my laughter down.

That's to say, I don't think it necessarily has to be from a med, I think some people just dream more vividly.

And I love your sig, Skillet is a great band and I love their music.
