Hyperesthesia

Hyperesthesia is a condition that involves an abnormal increase in sensitivity to stimuli of the senses.

Stimuli of the senses can include sound that one hears, foods that one tastes, textures that one feels, and so forth.

In the context of pain, hyperaesthesia can refer to an increase in sensitivity where there is both allodynia and hyperalgesia.

[1] In psychology, Jeanne Siaud-Facchin uses the term by defining it as an "exacerbation des sens"[2]: 37  that characterizes gifted individuals: for them, the sensory information reaches the brain much faster than the average, and the information is processed in a significantly shorter time.

Detection can be somewhat difficult as it is characterized by brief bursts of abnormal behavior, lasting around a minute or two.
