you had fallen onto the train tracks and gotten brain injuries, causing you to fall into a coma. and the patient nextdoor happened to fall into one too. a few months passed and the two of you woke up from that a coma though both of you were yet not fully healed, meaning you'd have to be in the hospital for a while longer. it was midnight, all the patients were asleep and you needed to use the bathroom. you got up from your bed, dragging the machine keeping your blood running with you.
