Yes, multiple times. I think the most times I've thought that I've woken up, only to figure out I'm still dreaming is five. It's really not a pleasant experience, especially since when it happens to me it's usually accompanied by very disturbing events. Without going into too much detail, disfigured faces coming out of the walls/dresser, a ghost flying into me, various large spiders, talking to my brother on a two way TV where my alarm clock usually is, sitting on a pile of clothes crawling with maggots. Shadows in the corner of my room moving around. The only time it's kind of cool is when there's zombies involved and I get to shoot them. They're really annoying though, because it seems completely real at the time, until either I realize that something just doesn't seem right and I'm probably still dreaming, or it becomes so distressing that I hope that I'm dreaming and try to wake up. Might be one of the reasons I hate going to sleep.
