A few days ago, my daughter and I watched the Adventure Time episode "Puhoy", in which an introspective Finn climbs deep into a pillow fort to let his thoughts ferment. He then encounters a pillow-people civilization and finds a new life. About halfway through, it struck me: this is, in essence, the plot of the Hugo-winning Next Generation episode "The Inner Light".
There's nothing more to say. Just an observation.
