Sounds like a lucid dream. I've had it a few times, last week I had one where I was really stressed about losing my backpack, and in my dream I said to myself "I don't want to be stressed about this, it's just a backpack, and I'm in a dream anyway", it was at that point where I realized I was dreaming so said to myself "so...if you don't want to be stressed about this, just wake up then", and upon waking, I was laughing at myself over how silly the experience was. It's quite fun, if you've done it once before, maybe you want to try it again?
