Is there a word in English (perhaps but not necessarily in medical jargon) to describe the disconnection between two related bodily perceptions, e.g.:
to feel tired, but not sleepy
to be hungry, but to have no appetite

I think part of the term you're looking for is "dissonance" which the Oxford Dictionaries defines as "Lack of agreement or harmony between people or things."
There is such a thing as "Sensory Dissonance", but that seems more related to physical sensations not jiving with reality (such as when you get into a cold pool because it seems warmer than being in the wind, even though it is in fact colder.) This is the closest I could come up with, however.
("Cognitive dissonance" is something else altogether, the ability to hold two or more contradictory opinions or beliefs.)
