After watching the episode of Untold Stories of the ER where a homeless lady with a schizophrenia-spectrum disorder made a series of incisions, stuffed them with dirt, and put earthworms inside them; someone eating potting soil wouldn’t surprise me…
The lady had names for each of the worms and would not let the doctors remove them, until they had maintenance bring them of dirt for each worm. The worms were put in individual containers which were labeled according to the names she had for each worm.
