Had an interesting moment in a dream last night. I was walking up a stairwell, but was simultaneously going down. This picture is the best way I can describe it: Maybe that image Daniel shared with the hidden circles in all those lines planted a dream seed in my head lol. Anyway, I was kind of impressed that my mind was able to create something like this, it was very trippy. Could be fun to experiment with things like this whilst lucid. If anyone else has experienced any mind-bending paradoxes or illusions during dreams, lucid or not, I'd love to hear. Or, just cool illusions in general to use for inspiration. I'll toss in some videos I came across as well to further explain what I'm talking about. The first is some kind of game engine that explains / simulates impossible and non-euclidean worlds (maybe this was a dream seed lol). The others are clips from Inception, similar to what I experienced (although slightly different, hard to describe). But it does showcase the paradox well.
