Well, hundreds of times I did. duno if it counts as a REAL false awakening but in my most recent dream (only napped for 30 minutes), i lived over a week or 2 inside dreamland, always waking up in the same bed. For the first 4-6 awakenings, i was oblivious to dreaming but after i became lucid i tried out some stuff. . . like using 'magic' powers, changing objects into something else, meeting people and making friends (lol how useless would that be.. :X ) and then ALWAYS something happens to me. I get hurt, i get killed, etc. and i wake up in the same bed... but i also heard the 'real' world thru my dream, such as people coming in and out of their dorm doors, the hall, etc...

and when i realise ive had enough of this freakish world i paniked and ATTEMPTED to force myself to wake up...

needless to say, i woke up again and again and again and again *MANY times, hundreds of times, waking up on the same bed and finally i got up i cried in my dream, i prayed to some unknown force to release me, that i was sorry for whatever i did... and tHEN i woke up. looked at the clock and a mere 30 min passed. . .

weird thing was, i was in positions in the dream such as in a hospital where i could ponder how ppl in a coma feel like. in so many life situations. so many problems. i cant help but think . . . was someone or something trying to teach me a lesson here??
