It all started when, after many years, I decided to meet up with some classmates. Perhaps the first dream in my life in which so many real people participated – maybe five. However, the other five or seven were, of course, made up, and my brain explained this as "well, you didn't study with us for very long, only four weeks."
Interestingly, when I arrived, right on time according to the backstory, everyone was already sitting at the table, quite tipsy, and almost asleep (well, actually, most of them had indeed seen the third dream). There's a noticeable difference compared to the graduation party; back then, only one person was slightly tipsy, but we've all grown up.
The second dream was semi-lucid. For some reason, I felt the urge to conduct an experiment and find another real person in my dream. Like, a completely real person. The test was that this person shouldn't participate in a suddenly organized... circle dance. Indeed, what sane, real person would suddenly want to join a crowd of people dancing shoulder to shoulder in the street? They definitely have to be a fictional character.
So, I saw some kid who was behaving quite naturally. I approached him and asked, "Are you not a person?" (mentally criticizing myself for the idiotic wording). But the idiotic circle dance pushed me from behind and didn't let me talk properly.
And the third dream continued the experiment in a similar vein. This time, the principle was that "no real person would suddenly start singing along with everyone else in the street." It was a failure because all the characters that appeared in my dream started singing.
Anyway, that's it.
