I did think of clarifying that the window is mostly large enough for AI dungeon to work. Though my understanding is that they do hit it if you go long enough, and the result is, well, exactly what you'd expect from that.

I did play with AI dungeon, and I would say the analogy to a dream is even deeper than it may appear at first, because I found that lucid dreaming techniques basically work on it, which is bizarrely impressive. I would characterize a lot of what one does in lucid dreaming (or, at least, what I do) is basically "expectations management"; if you can learn to expect something to happen in a dream, it frequently does. Not necessarily exactly what you "expected", but it will have a very significant influence. Correspondingly, it is possible (and indeed easy) to basically lead the AI along by using your text prompts to expect things to happen, and in a very dreamlike fashion, while that doesn't mean the exact thing you "expected" will be what the AI produces, it can clearly have very very significant impact on the result.

I should warn you this sort of removes the magic from AI Dungeon as an experience though... I have to consciously "let" it drive the story because it's pretty easy to exert much more control than you're "supposed" to have, when you know how to look behind the curtain.
