Regarding 3: "helpful" hallucinations are not that unusual. While most who hallucinate are tormented by demons, some hallucinate neutral observers and a few get a "guardian angel" who sometimes gives useful advice. The subconscious can definitely channel "you left the stove on" into a hallucination that commands the person to go turn off the stove. So transformation of awareness of ill-health into that sort of experience doesn't seem too preposterous.
