Not to be confused with, but in correlation with a high fever, a fever-high is the feeling of intoxication which results from an abnormally high
body temperature. Symptoms which are associated with a fever-high typically include: hallucinations (both visual and auditory), dizziness, irritability, weakness, confusion, and detachment from or the inability to perceive
reality. These symptoms are also known to occur while under the influence of such
drugs as psilocybin mushrooms (a.k.a. magic mushrooms) and other hallucinogens, hence the term fever-"high." Some of these symptoms can also be associated with the consumption of
alcohol.

fever-high last night. One benefit of being sick I guess.
Mitch: "Yeah bro, that shit is the next
best thing to shrooms."
Nelson: "Word."
