I sometimes get this too. I had a really horrible one last year. I dreamed I was in court, representing a mutant in a wheelchair. The mutant had let his able-bodied infant son play near a pond, but the kid had fallen in. A young couple standing nearby had filmed the kid and were laughing as he drowned, while his disabled dad pleaded for them to wade in and save him. They'd then posted the death footage all over social media.
I was aware the case was going really badly - I didn't have a fucking clue what I was doing. I was flicking through stacks of coffee-stained pages, all full of incomprehensible legalese, while the judge tutted and the young couple giggled and pulled faces. I woke up and spent an hour staring at the ceiling, arms folded across my chest. Can you prosecute someone for failing to save another's life, even if they didn't push the kid in? Is there legal precedent for it? I remembered reading about this custom in Rwanda where, if a woman gets attacked and cries out, any blokes nearby are obliged to drop everything and head in her direction: the police will rough up and interrogate anyone in the vicinity who stayed put or didn't respond. Could I work that into my case for the prosecution?
It was gone lunchtime and I was still stewing over this dream court case, looking up the UK's legal stance on duty to rescue instead of doing any work. It wasn't 'til mid-afternoon that I felt right again: but I still wanted to nail this fictitious couple and send them down for life. Fucked my day up, I felt properly down. Even though this whole case didn't exist outside of my hippocampus, it still pains me that they probably got off scot-free. Still, maybe they'll get nobbled by the vampire who cornered me in a public toilet during a flu dream when I was 8.
