I didn't do much exploring in this dream, but the people in my dream kept saying that it was similar to the Backrooms

  Most of my dream takes place in the "cafeteria" while other people explore

  I woke up in a cafeteria at one of those foldable lunch tables that schools have, along with around 20-30 other people

  Me and the other people ere all very confused and some people started freaking out

  In this dream, my middle school (from years 6 to 7, I left after 7th to another school) music teacher (or someone who looked very similar to her) began to try to get a hold of the situation

  It was at this point that I noticed people didn't have normal hair color

  It seemed we all came in with grey hair, and some of the people around had started gaining red hair

  I began to keep an eye on people while staying put on the table

  The genuine version of this novel can be found on another site. Support the author by reading it there.

  Over the course of like an hour (in dream time), I had noticed my hair began to change to a hue of green while others either still had grey or were gaining more of a vibrant red

  People began to leave the cafeteria and explore, This is when people began to tell me it was similar to the Backrooms

  After a while, a huge wave of blue foam balls began to cascade in from one of the doors, and they slowly swept through the cafeteria

  It turns out that if you gain too much red hair, by being rude to the space we were in, stealing, attacking others, or doing anything else normally deemed morally incorrect, you'd eventually get washed over by the blue balls and disappear

  At this point me and a few other people had green hair while most still had grey hair or very faint red

  But the few people who did have bright red hair were washed over and never seen again

  It turned out that my constant accidental "Sorry" to objects I bumped into led me to have the most vibrant green hair at the moment

  People began to notice that the blue balls began to actively avoid me and the other green-haired people

  They began to bug us about how to get green hair, and I'm pretty sure I had a long and lame speech, I forgot most of it though

  It went along the lines of, "Don't be an asshole and treat this place with respect" but add word filler to the point where you might fall asleep

  When everyone in the cafeteria reached a certain shade of green, the blue balls began to avoid them, and they set out, looking for a way out of the place

  I eventually woke up and had another weird dream, which ties into another dream I've had, I don't think I've written about it on this website, and it's kinda personal, so I think I won't write about it

  Have a nice day/night, depending on when you read this
