I find that when I LD, sometimes I can control when I can wake up. I don't usually do spinning, I just go on with the dream with the knowledge that I can choose to wake up when I want (when I have nothing to do the next day of course). Sometimes though, and this is odd, I feel like if I don't wake myself up I'll stop breathing. Does anyone else ever get this and/or is able to choose when to wake up?
