One of my favourites is from sometime in my last couple years of highschool.
I was a girl named Jane, and I was living in a dormitory or boarding school or something, and I knew that I had previously been in trouble for "spending too much money and being a bad influence on the other girls." There was a woman in a sharp pink suit who was kind of following and keeping an eye on me throughout the dream, and if I was caught doing it again there was a vague implication I'd be arrested or involuntarily committed or something. Anyway, in highschool IRL there was a quiet girl named Marie that I kind of idolised and was too shy to talk to; here in the dream she had started talking to me and wanting to hang out. I was extremely excited to do so, and we went out to the mall together with a couple of friends. When we went to the food court and sat down to order food -- it was set up like barstools at a bar in front of each restaurant for some reason -- I suddenly realised I'd messed up. I was spending money, and I was in trouble. I felt extremely guilty and dumb for falling back into this habit I'd sworn I wouldn't do again --- but then Marie took out her wallet, a ratty cloth wallet covered with patches, and she took out money to pay for our meals. I can't describe how relieved I was.
Suddenly, the best way I know how to say it is that the dream switched to a 3rd-person view. I saw what Jane looked like for the first time, a tall blonde girl sitting there with Marie on one side and her two other friends on the other, with a couple of unrelated customers in the other seats. Then the view shifted, and I realised what I was seeing there was still Jane's perspective -- she was seeing those other people, but in reality, there was no Marie. There were empty seats where the two friends had been. There was just Jane, by herself, holding the ratty cloth wallet and pulling out money to pay the man. And while I watched, the lady in the sharp pink suit walked up and dragged Jane away, screaming.
And then I woke up!
