Madness.

I seem to remember a series of nightmares a while back. In all of them nothing necessrily happened, but somehow, I knew I was going mad (insane) in all of them. These are the first nightmares that send me sitting bolt upright in bed, genuinely afraid, since I was in the 5th grade. They've not recurred since then, but it's had me slightly worried ever since.

Had anyone else had to deal with such dreams?
