So I lucid dream without trying( I dont know why) and I was just wondering if there's anyway to like prevent it because everytime i lucid "dream" im in a nightmare and am completely aware that i am dreaming. I always manage to wake myself up, but this time was weird because I woke up 3 different times IN my dream on my "bed" (as in my nightmare started over 3 different times and i had to keep going through the same thing) and i couldnt get out of my sleeping state. Does anyone have tips of how to get out of a lucid dream(nightmare)quickly? Or how to prevent it in general? Also why was my nightmare starting over everytime i tried to wake up?
