I was watching Rolling With Difficulty, and they had to pass through a portal that you can only enter if you're genuinely despondent. So Dani, the ship's engineer, imagines a world where everything is working and there's nothing left to fix, and she immediately drops through the portal.

It's hilarious because they were fighting a villain whose whole ideology is "entropy is inevitable, stop struggling to live", and he keeps trying to tempt Dani to his side, and he just does not understand her as a person because every time he says "everything is going to rust and fall apart", she says "great, then I'll have more stuff to fix".

Anyway Rolling With Difficulty is basically a Star Trek D&D campaign. They sail the astral sea between planes, seeking out strange new worlds.
