False sensations

False sensation(s) is the New Terran psychiatric term for any perception or feeling through one or more of the sense organs that is not caused by any real external or internal stimulus. Thus, the sensation is false. It is an umbrella term for visual hallucinations, auditory hallucinations, and even hypochondriasis (which is currently recognized as a somatoform disorder). False sensations are the symptoms of several perceptive cognitive disorders. 
==How to identity false sensations==
Terran psychiatrists usually identify false sensations from what a patient says and how they respond to the sensation.
==As a symptom of a perceptive cognitive disorder==
In Terran psychiatry, any false sensation, no matter how temporary, indicates a severe perceptive cognitive disorder. If not treated, according to the psychiatrists, the patient will develop more intense psychoses.
