Wanna share your dreams? Long story short, I had this creepy dream (thank you flu meds) that I was giving myself mouth to mouth in order to awaken the said self from sleep apnea (my breathing stopped). It was just strange dreaming about me sitting in my own bedroom, next to another me on the floor and trying to snap her out of that dream. I knew it was a dream because in it I washed my hands and noticed that my fingers were out of proportion. So I tried slapping her/me, but finally figured out that if it's the air that I\she needed, then CPR would make sense. And it did work - I woke up to find myself gasping for air. Apparently, I turned onto my back while sleeping and got a nice combo of nasal and chest congestion that resulted in temporary asphyxiation.
What's even funnier, I've been like that for a few years now - intervening into my own dreams and figuring out ways to awaken myself from whatever (whether it's a self-CPR or trying to get another person to wake me up). Way too self-aware.
