Hallucinations: When to Seek Help and What to Expect

Seek help for hallucinations whenever they are new, recurring, frightening, or getting in the way of sleep, work or relationships. Get emergency care if they start suddenly with confusion, fever, a head injury, a new medicine or drug use, or if the person is detached from reality or at risk of harm. Many causes are medical, and most are treatable.

This article is for adults, teens and family members in Texas who are worried about seeing, hearing, smelling or feeling things others do not. It explains causes, red flags and what an evaluation involves. It does not replace an in-person assessment, and some situations described here need a same-day visit or 911.

This article is general information, not a medical recommendation. Do not start, stop or change any medication without talking to your prescriber.

What counts as a hallucination?

A hallucination is a sensory experience that seems real but is not coming from the outside world. MedlinePlus defines hallucinations as sensing things such as visions, sounds or smells that seem real but are not.

Hallucinations can involve any sense:

• Hearing voices, music or sounds no one else hears.
• Seeing people, shapes, lights or animals that are not there.
• Smelling odors others cannot detect.
• Feeling touch, crawling or pressure on the skin.
• Tasting something unusual without a source.

Hallucinations are different from delusions, which are fixed false beliefs. The National Institute of Mental Health (NIMH) describes psychosis as a set of symptoms, including hallucinations and delusions, that disrupt thoughts and perceptions so a person may struggle to tell what is real.

Are hallucinations always a sign of mental illness?

No, hallucinations are not always a sign of mental illness. MedlinePlus lists grief as one example: briefly hearing the voice of, or seeing, a loved one who recently died can be part of mourning.

Other non-psychiatric situations include fever, especially in children and older adults, sleep disorders such as narcolepsy, and intoxication or withdrawal from alcohol and drugs. Some brief experiences when drifting off to sleep are not dangerous on their own.

What matters is the pattern. A single, brief, understandable experience is different from voices that return daily, visions that frighten you, or perceptions that come with confusion or fever.

What can cause hallucinations?

Hallucinations can come from medical illness, substances, sleep problems or mental health conditions, and sometimes more than one at once. MedlinePlus names severe illness such as liver failure, kidney failure and brain cancer, as well as mental disorders such as schizophrenia and psychotic depression.

• Medical causes: infections, high fever, brain conditions, and serious organ illness.
• Delirium: MedlinePlus describes delirium as sudden severe confusion, often triggered by infection or medicines, and advises contacting a provider for any rapid change in mental status.
• Substances: alcohol, cannabis, stimulants and other drugs, during use or withdrawal.
• Medicines: NIMH lists certain prescription medications among possible contributors to psychosis.
• Sleep deprivation: NIMH also lists lack of sleep.
• Mental health conditions: schizophrenia, bipolar disorder and severe depression, according to NIMH.
• Neurological illness in older adults: NIMH notes psychosis can accompany diseases such as Parkinson's or Alzheimer's.

When should you seek help for hallucinations?

Seek help for hallucinations promptly, within days, if they keep happening, are distressing, or come with changes in sleep, mood, thinking or functioning, even if the person seems otherwise well. NIMH advises contacting a health care provider if early warning signs of psychosis intensify or persist.

NIMH describes early warning signs that often appear before psychosis develops:

• Suspiciousness or paranoid ideas.
• Trouble thinking clearly or concentrating.
• Pulling away from friends and family.
• Sleep disruption.
• A decline in self-care.
• A sudden drop in school or job performance.

NIMH also states that early treatment often means better recovery. Waiting to see if things pass on their own is understandable, but it can delay care that works.

Red flags: when are hallucinations an emergency?

Hallucinations are an emergency when they arrive suddenly with confusion or physical illness, or when anyone's safety is at risk. MedlinePlus warns that many conditions causing hallucinations can quickly become emergencies and that the person should not be left alone.

Call 911 or go to the nearest emergency room if:

• Hallucinations start suddenly with confusion, fever, a severe headache, a seizure or a head injury.
• They began after a new medicine, an overdose, or stopping alcohol or another drug.
• Voices tell the person to hurt themselves or someone else.
• The person cannot care for themselves or seems completely detached from reality.
• An older adult becomes newly confused or agitated over hours to days.

For thoughts of suicide, the 988 Suicide & Crisis Lifeline is free, confidential and available 24/7 by call, text or chat. See our guide on what to do in a mental health crisis.

Lyte Psychiatry is an outpatient practice. It does not provide inpatient care, crisis or after-hours coverage, medically supervised detox, or intensive outpatient or partial hospitalization programs.

What to do if you or someone you love is hallucinating: step by step

Start by checking safety, then medical causes, then arrange an evaluation. MedlinePlus advises that a person who begins to hallucinate and is detached from reality should be checked by a provider right away.

1. Check immediate safety. Remove access to weapons, car keys or dangerous objects if there is any risk. Call 911 for danger.
2. Stay calm and stay close. Speak simply. You do not need to argue about whether the experience is real.
3. Look for physical clues. Fever, confusion, new medicines, alcohol or drug use, or a recent fall.
4. Get the right level of care. Emergency room for red flags; otherwise a same-day call to a primary care provider or psychiatric clinician.
5. Write things down. When it started, what is sensed, and what makes it better or worse.
6. Follow up. Even if symptoms fade, schedule an evaluation to look for the cause.

If voices or frightening thoughts recur, a written plan helps. Our mental health safety plan template shows what to include.

What to tell a clinician: a checklist

Clear details speed up the evaluation. MedlinePlus notes that a provider will take a medical history, including medicine, alcohol and drug use, do a physical exam and ask specific questions about the hallucinations.

• What you see, hear, smell, feel or taste, and when it first happened.
• How often it happens and how long each episode lasts.
• Whether you know in the moment that it is not real.
• Whether voices comment, argue or give commands.
• Recent sleep, stress, losses or major life changes.
• All medicines and supplements, plus alcohol, cannabis and other drug use.
• Medical conditions, recent illness, fever or head injury.
• Family history of bipolar disorder, schizophrenia or severe depression.

Our article on what happens at a first psychiatry appointment explains the rest of the visit.

How are hallucinations evaluated and treated?

Hallucinations are evaluated by looking for medical causes first and then for mental health conditions, and treatment depends on what is found. MedlinePlus notes that tests may include blood and urine tests or head imaging, depending on the situation.

When hallucinations are part of psychosis, NIMH describes antipsychotic medication as the usual base of treatment and identifies coordinated specialty care as a team approach for early psychosis. That team approach includes psychotherapy, family education, medication management, support for work or school, and case management.

Some people need more support than weekly visits can offer. Our guide to when weekly therapy is not enough explains intensive outpatient, partial hospitalization and inpatient care.

How can you support someone who is hearing voices?

Support someone who is hearing voices by staying calm, keeping things simple, and helping them reach care without arguing about what is real. NIMH notes that coordinated specialty care for early psychosis includes family education alongside therapy and medication management.

• Acknowledge the feeling: "That sounds frightening. I am here."
• Lower stimulation: turn off the TV, dim harsh lights, and limit visitors.
• Ask directly whether the voices are telling them to do anything.
• Offer practical help, such as driving to an appointment or making the call together.
• Look after yourself too. Supporting someone through psychosis is tiring, and your own therapy can help.

Texas crisis and community resources

Texas local mental health authorities run 24/7 crisis lines, organized by county. As of October 2026, Texas Health and Human Services lists the North Texas Behavioral Health Authority crisis line for the Dallas area at 866-260-8000 and MHMR of Tarrant County at 800-866-2465.

These authorities can often arrange mobile crisis help or an urgent assessment. If you live elsewhere in Texas, the same state page lists the crisis line for your county. Services and hours differ by area, so confirm details with your local authority.
