When i was very young i would act out the stories to distract myself from fear of the dark at night before i slept. It had utility in college and high school because i sometimes got tied up in knots of regret if i thought too much at late late hours. In industry, it made a great way to force my brain away from stress and thoughts of work. I just pick up roughly where i left off and play out the story until i am asleep.
(in fairness I find it entirely possible to wake up and spend a few moments weeding out the real from a dream)
In the middle of all this I was waking up and falling back asleep so I knew it was a dream and then I saw my kid running and thought I had to chase after him and some women said, "Just go do what you want" and instead of chasing after him I went and did what I wanted.
