It's weirdly common in my dreams to have low gravity or to have the ability to swim through the air. I'm pretty sure my brain is recognizing that gravity isn't applying to me in the way it should be if I were standing up (because I'm actually laying down in a bed), and my brain is just confabulating an explanation for it. So that makes me wonder whether that circumstance in your lucid dream (and choices in lucid dreams in general) is really happening because of your free choice, and whether the belief that you decided for that to happen is just part of your brain confabulating an explanation. I assume it and probably most decisions are a mix of both.
