Hallucinations: Types, Causes, and Management

Hallucinations

Hallucinations

A hallucination is defined as sensing things while awake that seem to be actual and physical while it is actually not real and has been created by the mind. Hallucination is sometimes normal, especially after a great life event, such as losing a loved, which is normally considered as part of the grieving process. In other cases, it is caused by a mental or physical illness or side effect of particular medications.

A hallucination should not be confused with an illusion. In hallucinations, there is a sensory perception while in the lack of an external stimulus. In contrast, in an illusion, there is an external stimulus but misperception occurs. This sensory perception may either be visual, auditory, olfactory, gustatory, tactile or proprioceptive. The different types of hallucinations will be described in detail later.

  • Observe for signs that a person is hallucinating, such as any of the examples given above.
  • If one is in an appropriate relation with the patient directly ask the patient if he/ she is experiencing hallucinations. Speak clearly and without being condescending. One may try asking:
    • Are you seeing someone else in the room?
    • Can you hear voices other than our own? What are they saying to you?
  • Do not deny the person’s experience but suggest own perceptions. One may try saying:
    • I understand that you are feeling worried but I do not see or hear anything.
  • If the patient can understand your conversation,
    • Assist the person in identifying symptoms and the triggers or hallucinations.
