I had to go back to high school for re-education. The dream fit in pretty perfectly with real life. I lost my job and will have to go back to school soon. So it's not like I traveled back in time, it was 2016, I graduated ages ago and the dream acknowledged this. I arrived on the courtyard, and felt some apprehension as I id not know anyone (and I was way older than everybody else). I somehow managed not to make a fool out of myself, what I certainly would have done 8 years ago (social anxiety, I used to be an even bigger loser than I am now). I chalked it up to experience. When the bell rang we had to stand in a line and do this weird sequence of arm gestures (hard to explain), which was apparently some kind of school ritual. It made perfect sense in the dream, not so much now. Anyway, I was confused as to where I should go and which classed I had to take. Then, a teacher addressed me and wanted to speak to me. They did not manage to finish their explanation, but I think they were wanted to say I shouldn't be in high school at all. I also remember tripping over something and almost falling.
