When people ask about the types of hallucinations in schizophrenia, they usually want two things: a clear explanation (in plain English) and practical next steps. Hallucinations are perceptions that feel real even though no external stimulus is present—most often hearing voices (auditory), but also seeing things (visual) or sensing smells, tastes, or touches that aren’t there. Understanding the types, how they show up day to day, and how they fit into positive and negative symptoms of schizophrenia helps you choose the right care—without panic or guesswork.
“Define Schizophrenia” (and why hallucination type matters)
Schizophrenia is a psychiatric condition marked by psychosis (e.g., hallucinations and delusions), disorganization, and negative symptoms like reduced motivation and expression—each can affect work, school, and relationships. Choosing treatment depends on which features dominate.
- Positive symptoms (added experiences): hallucinations, delusions, disorganized thinking/behavior.
- Negative symptoms (diminished functions): blunted/flat affect, alogia (reduced speech), avolition (low drive), anhedonia, and asociality.
- Why it matters: the type of hallucination you notice most (e.g., auditory vs. visual) can guide medication choices, therapy targets, and safety planning; auditory hallucinations are most common overall.
The 5 Core Types of Hallucinations in Schizophrenia
Hallucinations can involve any sensory modality. Below are the core types you’ll hear about most, plus everyday examples and clinical notes.
Auditory hallucinations (hearing voices or sounds):
- Everyday feel: hearing a running commentary, a second person talking about you, or commands.
- Notes that help care: ask about location (“inside vs. outside the head”), number of voices, content (commentary vs. commands), and what increases/decreases intensity (sleep loss, stress). Auditory hallucinations are the most common in schizophrenia.
Visual hallucinations (seeing things):
- Everyday feel: shadows, people, animals, flashes, geometric shapes.
- Notes: check lighting, sleep, substances, and medical contributors (e.g., vision problems). Visual events can co-occur with auditory ones.
Tactile/Somatic hallucinations (touch or bodily sensations):
- Everyday feel: crawling, burning, pressure, or internal movements without a cause.
- Notes: sometimes discussed as tactile (external touch) vs. somatic/visceral (internal bodily sensations). Clarifying which helps your clinician pick strategies.
Olfactory hallucinations (smell):
- Everyday feel: smoke, chemicals, foul or unusual scents others don’t notice.
- Notes: also seen in neurological conditions; clinicians consider a medical screen alongside psychiatric care.
Gustatory hallucinations (taste):
- Everyday feel: metallic, bitter, or odd tastes with no source.
- Notes: less common; may appear with olfactory events or certain medical conditions—report patterns carefully.
Beyond the “big five,” research describes rarer modalities like proprioceptive/kinesthetic (feeling body movement/position) and vestibular/equilibrioceptive (sensation of floating/spinning) in some contexts. These are less typical in schizophrenia but remind us that perception is multi-system.
How common is each type?
- Auditory > visual, with tactile, olfactory, and gustatory following—patterns vary by person and over time. Population studies and clinical samples consistently put hearing voices at the top.
- Multimodal hallucinations (two or more senses together or in sequence) occur for many people—tell your clinician if multiple senses are involved.
Positive vs. Negative Symptoms
Understanding where hallucinations sit in the bigger picture helps you ask sharper treatment questions.
- Positive symptoms: hallucinations, delusions (e.g., persecutory, grandiose), disorganized speech/behavior.
- Negative symptoms: affective flattening, alogia, avolition, anhedonia, asociality—the “5 A’s” often used in teaching. These predict day-to-day functioning and need targeted support.
What a Good Assessment Looks Like
A thorough evaluation should end with a plan you can run next week—not just a label.
- History + phenomenology: which types of hallucinations occur, frequency, triggers (sleep loss, stress, substances), safety risks (e.g., command content), and function (work/school/relationships).
- Structured screening: review of delusions (themes like persecutory or reference), disorganization, and negative symptoms (the “5 A’s”).
- Rule-outs & comorbids: medical conditions (neurology, sleep), substances, mood disorders.
- Treatment map: antipsychotic plan, therapy options, sleep and stress routines, and a relapse watch-list (early sleep changes + symptom upticks).
Treatment (integrated, evidence-based, and practical)
Care targets safety, symptom reduction, and function—measured weekly so progress is visible.
- Medication (foundation): antipsychotics reduce positive symptoms (including hallucinations). Choice/dose/timing are individualized; long-acting injectables can help with continuity.
- Psychological therapies: CBT-p (cognitive behavioral therapy for psychosis) to reframe beliefs about voices/visions and reduce distress/impact; family interventions to lower conflict and improve support.
- Rhythms & lifestyle: sleep regularity, morning light, steady routines—these stabilize arousal and often lower hallucination intensity.
- When symptoms persist: confirm adherence, rethink dose/timing, consider LAIs, address comorbid sleep or substance problems, and add structured coping skills.

FAQs about Types of Hallucinations in Schizophrenia
What type of hallucinations are most common in schizophrenia?
Auditory hallucinations (hearing voices or sounds) are most common across schizophrenia-spectrum disorders, followed by visual, then tactile/olfactory/gustatory—though patterns vary by person and over time.
What are the 8 hallucinations?
Clinically you’ll hear the “big five” (auditory, visual, tactile/somatic, olfactory, gustatory). Some sources also describe less common modalities like proprioceptive/kinesthetic (feeling movement/position when still), vestibular/equilibrioceptive (sensation of floating/spinning), and presence hallucinations. The goal isn’t memorizing terms—it’s describing exactly what you experience so care fits.
What are the 5 A’s of schizophrenia?
A teaching shorthand for negative symptoms: Affective flattening, Alogia, Avolition, Anhedonia, Asociality. Modern descriptions cluster these into “diminished expression” and “avolition,” but the “5 A’s” remain useful for remembering everyday impacts.
What are the 5 senses of hallucinations?
The “five senses” map directly: hearing (auditory), sight (visual), touch (tactile/somatic), smell (olfactory), and taste (gustatory). Tell your clinician which show up and when.
Which type of delusion is most common in schizophrenia?
Persecutory delusions (believing others intend harm) are frequently reported—especially around first-episode psychosis—though other themes like reference occur, too.
Understanding the types of hallucinations in schizophrenia turns fear into a plan. Start by naming what you notice (auditory, visual, tactile/somatic, olfactory, gustatory), when it appears, and what makes it louder or quieter. Pair that clarity with evidence-based care: steady medication, CBT-p, and sleep/stress routines. If you want one coordinated, online plan—measured each week so you can see progress—WNISS can help you get there.
