I had once a dream that my pager went off, and I woke up and looked at it, and it was just one of those status pages, that requires no action, so I went back to sleep...
then I hear ...beep... (reminder beep, goes off every minute)
Yeah, the pager did go off, but I did NOT wake up and look at it, and it was not a status page that I could ignore, but something I should get my butt out of bed and deal with. Tricky mind, lol!

Other time (and I am soooo glad it hasn't happened ever again. I told my mind if it EVER DID THAT AGAIN.. grrrr..) I was very tired, and I woke up because my bladder was very full, got up, put on slippers, waddled to my bathroom, sat down... you can guess the rest <blush> I woke up for real rather quickly, before too much happened. But gosh, it was so real.
