I had a dream the other night where I noticed inconsistencies between my constructed reality and actual reality, thus allowing the dream to become lucid. It was amazing to me how my brain could generate a crisp, clear image of hundreds of people walking around in an exact replica of the elementary school I went to. It was wonderful, until I tried to have some lucid dream sex, and was for some reason convinced I couldn't do it if I knew I wasn't actually naked, so I tried to make myself take off my shirt off in real life while staying asleep (not remembering about sleep paralysis), and then I woke up. But I didn't actually wake up, I just woke up into a bed in another dream with my shirt half off. This disappointed me, and then a little bit later I woke up in real life, with my shirt on, realizing how stupid I was for not just going along with the dream.
