Purple monkey dishwasher

This morning, since the ladies sitting near me on the train were screaming at the top of their lungs, well, ok they were just talking loud, I decided I might as well practice my french listening skills. From what I could understand, one of them was talking about someone who died in their sleep. Except she kept giggling so maybe I misunderstood? I distinctly heard, translated of course, "...feel asleep and just didn't wake up." Then, right after that, from what I understood, she spoke of someone who "glided" on the karate mat and now is paralyzed and that they are hoping they will get their feeling back but don't know. Except again, she kept giggling. Probably I missed a key word somewhere or something so I decided to tune them out and listen to the English people behind me instead. They were talking about some elderly lady who had died at the Christmas party but no one knew for a long time because they thought she was sleeping. "Ah hah!", I thought, they must have all gone to the same party! Maybe this woman had been to karate class before this bilingual Christmas party, paralyzed in a chair from "gliding" on the karate mat and fell asleep and died. Makes perfect sense. I am good at french.
