First lucid dream in a long time

Date: 5/8/2019

I don't remember how I became lucid, it was a really long dream, but I remember flying around a lot of the time, I was able to ask a few dream figures what they represented, and met with a group of other guys who seemed to have been in this dream world for a long time. One of them talked about getting out, another of them seemed like he was crazy for wanting to leave. Every time the dream started to slip away I was quick to look at my hands and remind myself I was dreaming. Eventually it did slip away from me and I became nonlucid and ending up being back at my highschool classroom.
