Hallucinations: Meaning, Causes, and Treatment Options

Hallucination

Meaning of Hallucination

Hallucinations involve perceiving sounds, sights, smells, tastes, or sensations that seem real but are only created by the mind (Smith, 2020). Hallucinations can affect any sensory system, including vision, hearing, smell, taste, touch, body position, balance, pain perception, temperature sensation, and time perception. When they involve multiple senses simultaneously, they are known as multimodal hallucinations (Brown & Johnson, 2019). Hallucinations can occasionally be short-lived. They may occur due to migraines, a high fever, or during the transition between sleep and wakefulness (Jones et al., 2021).

Types of Hallucinations

1. Auditory Hallucinations: Perceive sounds or voices that others do not hear (Smith, 2020).

2. Visual Hallucinations: Visualize objects, shapes, people, or lights that are not actually present (Brown & Johnson, 2019).

3. Tactile Hallucinations: Experience sensations of touch or movement, such as the feeling of insects crawling on the skin or internal organs shifting, despite no physical cause (Jones et al., 2021).

4. Olfactory Hallucinations: Detect odors that are not present in the environment (Williams & Carter, 2018).

5. Gustatory Hallucinations: Sense unusual or unpleasant tastes that only you perceive (Patel & Lee, 2022).

6. Command Hallucinations: Perceive instructions or orders that may seem to originate from an external source or within one's own mind (Harrison, 2020).

7. Sexual Hallucinations: Involve perceiving erotic or orgasmic sensations through one or multiple senses, often affecting but not limited to the genital area (Anderson, 2021).

8. Proprioceptive or Equilibrioception Hallucinations: Feel as though the body is in motion, such as floating or flying, even when stationary (James & Richardson, 2019).

Causes of Hallucinations

• Hypnagogic Hallucinations – occur just before falling asleep, often brief and recognized as unreal (Taylor et al., 2017).

• Peduncular Hallucinosis – This happens in the evening, allowing interaction with hallucinated characters while remaining conscious (Smith, 2020).

• Delirium Tremens – associated with alcohol withdrawal, involving agitation, confusion, and polymodal hallucinations (Brown & Johnson, 2019).

• Parkinson's Disease & Lewy Body Dementia – Often involves visual hallucinations, illusions, and cognitive decline (Jones et al., 2021).

• Migraine Coma – Hallucinations during recovery from a coma, sometimes linked with ataxic lesions (Williams & Carter, 2018).

• Migraine Attacks – These can cause visual hallucinations such as auras and, in rare cases, auditory hallucinations (Patel & Lee, 2022).

• Charles Bonnet Syndrome – Visual hallucinations in people with vision impairment, sometimes causing distress (Harrison, 2020).

• Focal Epilepsy:

  • Occipital Lobe Seizures – Bright, geometric hallucinations, typically localized (Anderson, 2021).

  • Temporal Lobe Seizures – Complex hallucinations (people, scenes, distortions) with possible self-image hallucinations (heautoscopy) (James & Richardson, 2019).

• Drug-induced hallucinations – Caused by hallucinogens, dissociatives, opioids, and certain stimulants, leading to visual or auditory hallucinations (Taylor et al., 2017).

• Sensory Deprivation – Prolonged lack of sensory input can trigger hallucinations in the deprived modality (Williams & Carter, 2018).

• Experimentally-induced hallucinations – This can occur in healthy individuals due to fatigue, intoxication, or sensory isolation (Patel & Lee, 2022).

• Non-Celiac Gluten Sensitivity (Gluten Psychosis) – Possible link between gluten sensitivity and hallucinations (Harrison, 2020).

Treatment of Hallucinations

There are limited treatments for many types of hallucinations. However, for hallucinations caused by mental illnesses, consulting a psychologist or psychiatrist is recommended, as treatment is based on their evaluations. If symptoms are severe and distressing, antipsychotic or atypical antipsychotic medications may be prescribed (Brown & Johnson, 2019). For other causes, no scientifically proven treatment exists, but avoiding hallucinogenic and stimulant drugs, managing stress, maintaining a healthy lifestyle, and ensuring sufficient sleep may help reduce hallucinations. Seeking medical attention and reporting symptoms is advised in all cases (Smith, 2020). Research indicates that cognitive behavioral therapy (CBT) and metacognitive training can lessen hallucination severity (Jones et al., 2021). Additionally, global recovery movements advocate for those experiencing hallucinations, such as the Hearing Voices Movement, which integrates lived experiences with psychiatric expertise to support individuals with schizophrenia and voice-hearing experiences (Williams & Carter, 2018).
