I had a friend with some type of terminal cancer and had a tube in her throat, requiring a machine to breathe.
We heard of this symbiotic alien organism that would live in your chest, acting as super lungs that would let you breath under water, eliminate respiratory problems, etc. She took one and it was so miraculous a recovery that we went all over, convincing healthy people to take this miracle symbiont to improve their lives.
Turns out this alien didn’t do well in human bodies and would spontaneously die after about six months, rendering what was left of our lungs as useless tatters. A death sentence.
The tail end of my dream was me going to everyone I had convinced to “fix” their lungs to tell them they were going to die. It was not a fun chore and fuck you, brain, for inflicting that experience on me. Ok
This is my instance.
