This question came to mind today, as every few months I have an instance of false awakening, which is kinda frustrating and a bit scary. In fact I thought I was alone in this problem until I stumbed across it in Wikipedia. For instance this morning I woke up, reached over and pulled the string to turn on my compact flourescent torchiere. It didn't come on... friggin' CF bulb burned out. Then I remembered my alternate torchiere. It didn't come on either! So there I am in the dark, feeling a twinge of panic, then I realized I had no torchieres! (panic!!) Before I know what happened I came into another waking routine in another bed, thinking "glad that's over". Except then I realized the colors were a bit eerie and I didn't recognize the bedroom at all. Soon after that I woke up. Thankfully there is not a shred of doubt when the real awakening occurs. I have had more vivid episodes before where I knew I was dreaming and was trying to wake myself by going back to sleep or focusing -- then I'd spring into another false awakening. How about you all? Any weird experiences, or just plain old nightmares? I have to say that sleep is such a strange and formidable thing that I don't like thinking about it while drifting off. I've found titles like Hobson's Chemistry of Conscious States to be scary bedtime material, yet ironically I've never had any problem with Lovecraft or M. R. James' ghost stories.
