What Are Hallucinations?
Hallucinations are PERCEPTIONS that people experience but which are NOT caused by external stimuli/ input. However, to the person experiencing hallucinations, these perceptions feel AS IF THEY ARE REAL and that they are being generated by stimuli/ input outside of themselves (in fact, of course, the perceptions are being INTERNALLY GENERATED by the brain of the person who is experiencing the hallucination).
Different Types Of Hallucination :
There are several different types of hallucination and I summarize these below :
- VISUAL HALLUCINATIONS – these involve ‘seeing’ something that in reality does not exist or ‘seeing’ something that does exist in a DISTORTED / ALTERED form.
- AUDITORY HALLUCINATIONS – these, most often, involve ‘hearing’ voices that have no external reality (though other ‘sounds’ may be hallucinated, too).
- TACTILE HALLUCINATIONS – these occur when an individual feels as if s/he is being touched when, in fact, s/he isn’t (for example, feeling the sensation of insects crawling over one’s skin).
- GUSTATORY HALLUCINATIONS – these occur when a person perceives a ‘taste’ in his/her mouth in the absence of any external to the person causing the taste.
- OLFACTORY HALLUCINATION – this type of hallucination is sometimes also referred to as phantosmia and involves perceiving a smell which isn’t actually present.
