Jen,
Im no expert but youre probably hallucinating because of the lack of sleep. Be careful with that Tylenol Pm...it contains acetaminophen which can actually cause hallucinations if you reach a toxic level. My grandmother wound up seeing people holding flags in her living room as a result of too much. Is there anyway the Doc. can increase the dose of your sleeping pill? Stupid question, Im sure you have already tried that but thought I'd ask anyway.
