What To Do When Someone Is Hallucinating | Stay Calm, Safe

Watching someone react to things you can’t see or hear can rattle you. Your goal is simple: keep everyone safe, lower fear, and bring in medical care when signs point that way.

Hallucinations can come with fever, medication reactions, intoxication or withdrawal, delirium, or a long-running mental health illness. You don’t have to pin down the cause. You do have to handle the next minutes well.

What Hallucinations Can Look Like

Hallucinations are sensory experiences that feel real to the person. They may hear voices, see people or animals, smell smoke, feel insects on skin, or taste something odd.

Some people know the experience isn’t real. Others feel certain it is. Either way, fear can spike and behavior can turn unpredictable.

Don’t assume it’s “just mental.” A sudden change, especially in an older adult or someone who’s sick, can signal delirium or another urgent medical problem.

What To Do When Someone Is Hallucinating: First Steps At Home

Start with safety and a steady voice. If the room stays calm, you gain time to decide what kind of help is needed.

Make The Space Safer

• Scan for hazards: knives, tools, glass, open flames, traffic, stairs, balconies.
• Give the person room. Stand to the side and keep a clear path to the door.
• Lower noise and activity. Turn off the TV, dim bright lights, and ask bystanders to step back.
• If they’re holding something risky, don’t grab it. Ask in plain words: “Please put that on the table.”

Use Words That Lower Fear

Aim for calm, short sentences. Keep your tone even.

• Start with a check-in: “You look scared. I’m here with you.”
• Name what you see: “I don’t see it, but I can tell it feels real for you.”
• Offer a choice: “Do you want to sit on the couch or at the table?”
• Ask what helps: “What usually helps when this happens?”

Avoid arguing about what’s real. You can validate feelings without validating the hallucination.

Check For Immediate Danger

Ask direct questions in a neutral voice.

• “Are you thinking about hurting yourself or anyone else?”
• “Are the voices telling you to do something?”
• “Do you feel safe right now?”

If there’s a risk of harm, call your local emergency number right away. Stay nearby until help arrives, unless your own safety is at risk.

Look For Medical Red Flags

Call emergency services if you see any of these:

• Sudden confusion, new slurred speech, weakness on one side, severe headache, seizure, or fainting.
• High fever, stiff neck, trouble breathing, bluish lips, or chest pain.
• Severe agitation, inability to sleep for days, or signs of severe dehydration.
• Recent head injury, carbon monoxide exposure, or ingestion of unknown pills or chemicals.

Quick Clues That Change What “Next” Looks Like

Once everyone is safe, gather details. You’re not making a diagnosis. You’re collecting facts that can change urgency.

Start with timing. Did it begin suddenly within hours, or build over days? Sudden change leans toward a medical trigger like delirium, infection, low oxygen, medication reaction, intoxication, or withdrawal.

Then check context: new meds, missed meds, recent drinking or drug use, poor sleep, or a new illness. If you can, note other symptoms like shaking, sweating, vomiting, or a racing pulse.

Public health and medical references that summarize hallucinations and care-seeking can help you frame what you’re seeing, such as the MedlinePlus overview of hallucinations and the NHS page on hallucinations and hearing voices.

How To Respond Without Escalating The Moment

During an episode, your tone can lower fear or add fuel to it.

Moves That Tend To Help

• Stay steady. Breathe slowly and speak at a normal pace.
• Keep your hands visible. Sudden moves can feel threatening.
• Offer grounding cues: “Let’s feel the chair under your legs,” or “Hold this cold bottle.”
• Use short questions: “What are you hearing?” “Where does it seem to come from?”

Moves That Often Backfire

• Blocking exits, crowding, or standing over them.
• Touching without asking.
• Laughing, teasing, filming, or arguing about “reality.”
• Demanding a long explanation while they’re distressed.

Common Triggers, Clues, And Safer Next Steps

This table lists patterns people notice around hallucinations. Use it to choose a next step, not to label anyone.

Table 1: Common Triggers, Clues, And Safer Next Steps

Possible Trigger	Clues You May Notice	What To Do Right Now
Delirium from infection or illness	Sudden confusion, worse at night, new trouble tracking a conversation	Seek urgent medical evaluation; stay close if fall risk is high
Fever or severe dehydration	Hot skin, dry mouth, dizziness, poor intake	Call urgent care or emergency services based on severity
Low blood sugar	Sweating, shaking, confusion, diabetes history	If awake and able to swallow, give glucose (juice, gel); call for help if not improving
Alcohol withdrawal	Tremor, sweating, agitation after stopping heavy drinking	Get medical help; severe withdrawal can be dangerous
Drug intoxication	Unusual energy, paranoia, sudden behavior change	Keep the room calm; call poison control or emergency services if severe symptoms
Medication side effect or interaction	New prescription, dose change, missed doses	Write down names and doses; seek urgent evaluation if confusion is severe
Sleep loss	Days with little sleep, racing thoughts	Reduce stimulation; arrange same-day evaluation if the person can’t settle
Seizure-related	Odd smells, post-episode confusion, tongue bite, incontinence	Call emergency services for a first seizure, injury, or breathing trouble
Long-running mental health illness	Past episodes, stopped meds, rising paranoia	Use the person’s existing care plan if you have it; seek urgent care if safety changes

When To Call For Emergency Help

If you’re unsure, lean toward safety. New hallucinations with confusion, fever, breathing trouble, or a sudden behavior shift call for urgent evaluation.

Delirium is one medical condition linked with sudden confusion and can include hallucinations; Mayo Clinic notes it needs prompt medical attention and that family observations can help clinicians. See Mayo Clinic’s delirium symptoms and causes for warning signs clinicians use.

Call Emergency Services Now If Any Of These Apply

• The person has a weapon, is trying to run into traffic, or is threatening harm.
• The voices or visions are commanding action, and the person feels compelled to obey.
• There’s severe confusion, inability to recognize familiar people, or sudden inability to walk safely.
• There’s a seizure, fainting, chest pain, blue lips, or severe breathing trouble.
• You suspect poisoning, overdose, carbon monoxide exposure, or a dangerous withdrawal.

Table 2: Where To Get Help Based On What You See

What You Notice	What It Can Signal	Best Next Step
Threats of harm, weapons, running into danger	Immediate safety risk	Call emergency services and keep distance
New confusion with fever or illness	Delirium, infection, low oxygen	Emergency evaluation, especially in older adults
Seizure, fainting, new weakness, slurred speech	Neurologic event	Emergency services now
Possible overdose, poisoning, unknown pills	Toxic exposure	Call emergency services or poison control
Withdrawal signs after stopping heavy alcohol	Withdrawal can worsen	Urgent medical care; don’t leave them alone
Known mental health illness, safety stable	Relapse or medication gap	Same-day clinic, on-call clinician, or emergency care if risk rises
Hallucinations near sleep onset or waking	Sleep-related phenomenon	Track it; seek care if it’s distressing or persistent
You feel stuck and fear self-harm risk	Crisis need	Use a crisis line or emergency services

If Self-Harm Risk Shows Up

If the person talks about dying, self-harm, or you feel stuck, reach out for immediate crisis help. In the U.S., the 988 Lifeline page on helping someone else lists ways to connect by call, text, or chat. Outside the U.S., use your country’s emergency number or a local crisis line.

What To Write Down Before You Reach Care

Clinicians move faster when you bring clean details. Use phone notes or a scrap of paper.

• Start time and how quickly things changed.
• New illness signs: fever, cough, pain with urination, vomiting, poor intake.
• Substances: alcohol amount, last drink time, any drugs taken, or withdrawal signs.
• Medications: names, doses, recent changes, missed doses, OTC meds, supplements.
• Medical history: diabetes, seizures, dementia, kidney or liver disease, recent surgery.
• Safety notes: threats, command voices, attempts to flee.

If you can bring pill bottles or a medication list, do it. If the person has a prior care plan, bring that too.

Ways To Help Once Things Start To Settle

After the peak passes, the person may feel ashamed, exhausted, or confused. Keep the next hour simple.

• Offer water and a small snack if swallowing is safe.
• Keep lights soft and noise low.
• Stay nearby, but give personal space.
• Let them rest. Save heavy conversations for later.

A Plan For Repeated Episodes

If hallucinations happen again, a plan can lower panic next time. Build it when the person is steady and willing to talk.

• Write the person’s early warning signs in their own words.
• List who to call, where to go, and the local emergency number.
• Lock up firearms, knives, and medications; keep car access fob in one spot.
• Pick a quiet room where the person can sit with low stimulation.
