I'm pretty sure this was a false awakening, but i'll describe it in case it happens to be something different.
I had a dream where i was at school and i was throwing bean bags or something at people. I kind of figured this is something i wouldn't normaly do at school, thats when i became lucid... within a few seconds i blacked out, then i thought "Damn, i'm waking up. I didn't get a chance to do anything!" but i started seeing these flashing lights and the inside of my eyelids. I felt like i was falling. When i suposedly "woke up" i was looking around, and my room was different, so I knew I was still dreaming, but i kind of had doubts. So i ran up stairs and there were a few things that were wrong, (the couches were arranged differently and there were 2 christmas trees in the family room.)
I still couldn't fully convice myself this was a dream... and at about that time my alarm woke me up.

Yeah, thats about it. I just thought i'd let people know about my wierd experience.
