Waking life anecdote:
We got some friends visiting this week, and today while preparing breakfast my wife said to us: "Last night I dreamt that I had to do a lecture but I didn't have any notes or remembered what I had to say, so I realized I was dreaming and tried to wish myself awake. I still feel terrible for that dream"
Ovbiously I was like "Whaaaaaaaaaaaaaaat?!?!" She saw my face and added "Yes, it happens from time to time, I'm going through a bad time and I sort of know am dreaming, so I wish myself awake"
At this point I knew I had to seize the opportunity, but I know my wife opinion on dream-related stuff, so I just said "As it was a dream you could have just got to fly away" They laughed like that was ridiculous, so I added: "When I have a fly dream, I wake up feeling wonderful. I you had flown away you'd feel great now" They giggled but I believe I made them think about it.
Five minutes later we were talking and joking, and my wife said something to tease me, so I paused and said "I better just fly away from this" and extended my arms superman style. Everyone got it, and burst in laughter
I think I'm going to use the "I'm just flying away from this" joke from time to time in the hopes that it sticks in my wife's SubC, pops up in a dream, and she gets a taste of lucidity!
