When someone is hallucinating, the most important thing you can do is stay calm, acknowledge their distress without pretending to share their experience, and avoid arguing about what’s real. What they’re perceiving feels completely genuine to them, and your goal isn’t to correct their reality but to help them feel safe. How you respond in those moments can be the difference between the situation calming down and it spiraling.
Hallucinations are more common than most people realize. Epidemiological studies estimate they occur in 6 to 15% of the general population, and they aren’t limited to psychiatric conditions. Fever, infections, sleep deprivation, medication reactions, alcohol withdrawal, and heatstroke can all trigger them. Understanding this matters because the person in front of you isn’t “crazy.” Their brain is generating sensory input that feels as vivid and real as anything you’re experiencing right now.
Start With Safety, Then Connect
Before you say anything, take a quick read of the situation. Is the person physically agitated? Are there objects nearby that could be thrown or used to harm themselves or you? If there’s any sign of aggression or a weapon, move yourself to safety first and call emergency services. People who are hallucinating range widely in behavior: some are quietly distressed, while others are paranoid with poor reality testing and pose a real physical risk. Don’t assume either extreme.
If the situation feels manageable, position yourself where the person can see you clearly but you aren’t blocking their exit. People who feel trapped escalate faster. Keep your body language open: hands visible, posture relaxed, no crossed arms. Stand at a slight angle rather than squaring up directly in front of them, which can feel confrontational.
Once you’ve ensured basic safety, your first job is simply to engage. Make eye contact if they’re willing, speak in a calm and steady voice, and use their name. You’re not trying to fix anything yet. You’re just letting them know another human being is present, paying attention, and not afraid of them. This initial connection is the foundation for everything else. The American Association for Emergency Psychiatry recommends a three-step approach: verbally engage the person, build a collaborative relationship, and then help them de-escalate. Rushing to step three without the first two rarely works.
What to Say (and How to Say It)
Your tone matters more than your exact words. Speak slowly, use short sentences, and keep your voice low and even. If you sound anxious, they’ll pick up on it.
The single most effective thing you can say is some version of: “I can see you’re really upset. How can I help you?” This does two things at once. It validates their emotional experience without confirming or denying the hallucination itself, and it hands them a small piece of control by inviting them to tell you what they need.
Here are specific phrases that work well:
- “I can see that’s frightening for you.” Acknowledges the emotion directly.
- “I don’t see/hear what you’re describing, but I can tell it feels very real to you.” Honest without being dismissive.
- “You’re safe right now. I’m here with you.” Grounding and reassuring.
- “I don’t really understand what that means. Can you tell me more?” Shows you’re listening without pretending to share the experience.
- “I can see you don’t want to talk right now. I’ll be right here if you change your mind.” Gives them space without abandoning them.
Keep checking in. Ask simple yes-or-no questions if they seem overwhelmed. “Are you in pain?” “Do you want to sit down?” “Would it help if I turned on the light?” Small, concrete questions are easier to process than open-ended ones when someone’s brain is already overloaded.
What Not to Do
The biggest mistake people make is arguing. When you say “That’s not real” or “Nobody is there,” you’re not being helpful. You’re telling someone that what they can see, hear, or feel with absolute certainty is a lie. From their perspective, you’re the one who’s wrong, and now you’re also untrustworthy. This typically increases fear and agitation.
Don’t laugh, even nervously. Don’t whisper to someone else in the room, because a person who’s already paranoid will assume you’re talking about them. Don’t touch them without warning or permission. Don’t crowd them. Don’t raise your voice, even if they raise theirs.
It’s also important to manage your own reactions. When someone says something bizarre or frightening, your instinct might be to recoil, get defensive, or try to reason them out of it with logic. Experts in psychiatric crisis management emphasize that clinicians and caregivers need to recognize their own tendencies to argue, retaliate, or become defensive, because those reactions reliably make the situation worse. If you notice yourself getting frustrated, take a breath. You don’t have to solve anything. You just have to stay steady.
Change the Environment
The physical space around someone can intensify or reduce hallucinations, particularly visual ones. Research on people with dementia-related hallucinations has shown that specific environmental triggers, like patterned carpets, clothes hanging on walls, dolls, or dim lighting, can cause the brain to “fill in” visual information incorrectly and generate hallucinations.
If you’re with someone who is hallucinating, try these adjustments:
- Increase the lighting. Shadows and dim rooms make visual hallucinations more likely. Turn on overhead lights or open curtains.
- Reduce noise. Turn off the TV, radio, or anything creating background sound. Competing auditory input can worsen auditory hallucinations.
- Simplify the visual field. Remove clutter, put away items with complex patterns, and fold or store hanging clothes that could be misinterpreted as figures.
- Minimize mirrors. Reflections can be confusing or frightening during a hallucination.
These changes won’t stop a hallucination in progress, but they can lower its intensity and reduce the chance of new ones being triggered.
Adjusting Your Approach by Cause
How you communicate should shift depending on what’s causing the hallucination. The distinction between a neurodegenerative condition like dementia and a psychiatric condition like schizophrenia changes not just treatment but the kind of support the person needs from you.
For someone with dementia, hallucinations are often visual: seeing people, animals, or objects that aren’t there. These individuals may have limited ability to reason about what they’re seeing, and attempting to explain it away can cause confusion and distress. Gentle redirection works best. You might say, “Let’s go to the kitchen and have some tea,” shifting their attention rather than challenging what they see. Physical grounding, like holding their hand or guiding them to a familiar chair, can also help reorient them.
For someone with a psychotic disorder like schizophrenia, hallucinations are more commonly auditory: hearing voices that others don’t hear. These individuals may have more capacity for conversation but can be deeply suspicious. Avoid phrases that sound clinical or controlling. Focus on the collaborative approach: “What do you need from me right now?” Treat them as a partner in figuring out the next step, not as a problem to be managed.
For hallucinations triggered by something temporary, like a high fever, medication side effect, urinary tract infection, or severe sleep deprivation, the hallucination will typically resolve when the underlying cause is treated. In these cases, your main job is reassurance. Let the person know this is a known effect of their condition and that it will pass. If you suspect a physical cause like infection, especially in an older adult, getting medical attention promptly matters.
When the Situation Becomes an Emergency
Most hallucinations are distressing but manageable. Some are not. Call emergency services if the person is threatening to harm themselves or someone else, if they are physically aggressive, if they have a weapon, or if they are so disoriented that they cannot respond to you at all. A person who is quietly delusional can still be at risk of self-harm, so don’t assume that calm means safe.
If you do call for help, stay on the line and follow the dispatcher’s instructions. When responders arrive, give them a brief account of what the person has been experiencing, any known psychiatric or medical diagnoses, and any medications they take. This information helps the medical team choose the right approach quickly.
While you wait, keep doing what you’ve been doing: stay calm, keep your distance if there’s any aggression, and speak in a low, steady voice. You don’t need to fix the hallucination. You just need to hold the space until help arrives.
