Short Stories with Tragic Endings

I have attempted a MILD and finally fall asleep after being kept up for a while by my mantra.
I have a very unique dream. I have only had one other like it in my entire life. My
vision was black and I was literally just thinking. No body, no sounds. Just visualizations and
thought. The subject of these thoughts was lucid dreaming. The one time I did this before was
about recursive methods in programming which I was only able to describe as a "dream in code".
I remember having a "eureka" moment with something in that subject area but I didn't remember
what it was when I woke up.
