There are two theories that are established to portray sensation of unified bodily feeling. One of these theories is called associationism, which states that cenesthesia is an amalgamation of propioceptive and interoceptive sensations. Faculty psychology is the other theory which states that there is a particular brain region where all of the sensory information converged and the integration of this information gives one cenesthetic sensation.

On the other hand, patients with "paraesthetic" cenesthopathic hallucination experience severe hallucinatory itching.
