Lighting Adaptations for Hallucinations During Emergencies

When an emergency strikes—like a power outage, storm, or sudden darkness—the wrong lighting can turn shadows and reflections into terrifying hallucinations for a person with dementia. This guide helps you provide safe, calming light without triggering or worsening visual hallucinations. You'll learn exactly what to do step by step, what products and phrases work best, and how to adapt for different types of dementia and stages. You are not alone; there are concrete, gentle ways to bring safety and calm.

Key points

  • During an emergency, use soft, warm, indirect light—never bright overhead lights or flashlights pointed at the person.
  • Stay calm and use simple, reassuring phrases: 'I am here. We are safe. Let me get some light.' Do not argue about what they see.
  • Pre-pack an emergency lighting kit with a warm LED lantern, battery candles, a power bank, and a list of calming phrases.
  • Natural light is best—open curtains during the day, even if overcast. At night, use soft artificial light and close curtains to block confusing shadows.
  • If the hallucination is not bothering them, you do not need to intervene. If it is, validate their feeling, then redirect to a simple activity or a different room.
  • Different dementias (especially Lewy body) require extra caution with light—avoid flickering, pulsing, or bright light. Always consult a clinician before using medications for hallucinations.

Why Darkness and Poor Light Trigger Hallucinations

In dementia, the brain's ability to correctly interpret what the eyes see is damaged. Shadows, reflections, and sudden changes in light can be misread as people, animals, or threatening objects. During an emergency—like a power outage or a storm that darkens the home—the environment becomes unpredictable. The person's brain, already struggling, may fill in the gaps with frightening images. This is not 'seeing things' on purpose; it is a symptom of the disease, and it feels absolutely real to them. The goal is not to argue, but to provide lighting that reduces those misinterpretations.

The Role of Natural and Artificial Light in Calming Hallucinations

Research and expert guidance show that hallucinations often subside in well-lit areas where other people are present. Bright, even light reduces shadows and helps the brain distinguish real objects from imagined ones. During an emergency, you may not have your usual lights, but you can still create a calming environment. The key is to avoid harsh, flickering, or directional light that casts strong shadows. Instead, aim for soft, diffused, warm light that mimics natural daylight as much as possible. This helps the person's brain feel safe and oriented.

What Happens in the Brain During a Hallucination Emergency

When a person with dementia hallucinates, the brain's sensory processing regions are misfiring. They are not choosing to see things; their brain is presenting them with a false but convincing reality. In an emergency, stress hormones rise, making the brain even more prone to misinterpretation. The person may feel trapped, scared, and unable to trust what they see. Your calm presence and the right lighting can lower that stress, giving the brain a chance to settle. Remember: if the hallucination is not bothering them, you may not need to intervene. But if they are frightened, your response matters deeply.

Step-by-step

  1. Stay calm and speak in a low, soothing voice. Say, 'I am here with you. We are safe. Let me get some light so we can see better.' Do not argue about what they see.

  2. If the power is out, use a battery-powered lantern or flashlight with a warm, diffused glow—not a bright white beam. Place it on a table or counter, pointing upward or toward a wall, to create indirect light. Avoid shining it directly into their eyes or at the area where they see the hallucination.

  3. If you have a backup power source (like a portable power station or generator), plug in a small lamp with a soft, warm bulb (2700K-3000K color temperature) and place it in the room where you both are. Avoid overhead lights that cast harsh shadows.

  4. If you have a smartphone or tablet, use it to play a calming video of a fireplace, aquarium, or nature scene with soft, warm light. Set the screen brightness to medium and place it across the room—not in their direct line of sight. This provides gentle light and a soothing focal point.

  5. Open curtains or blinds if it is daytime, even if the sky is overcast. Natural light, even on a cloudy day, is far better than darkness. If it is nighttime, close curtains to block out confusing streetlight shadows, then use your soft indoor light source.

  6. If the person is upset by a shadow or reflection, gently guide them to a different seat or room. Say, 'Let's go sit over here where the light is better.' Do not point at the shadow or say 'that's just a shadow'—they cannot process that.

  7. Offer a simple, comforting activity that involves light or touch: hand them a warm cup of tea (if safe), ask them to hold a soft blanket, or play a familiar song on a battery-powered speaker. This shifts their focus away from the hallucination without directly challenging it.

  8. If the emergency is ongoing (e.g., a long power outage), set up a consistent 'safe zone' with a battery lantern or candle-free LED light that stays on. Check on them every 15-20 minutes, using the same calm phrases each time to build predictability.

  9. If the hallucination involves seeing a person or animal, you can validate and redirect: 'I see you are concerned about that person. They look like they are just passing by. Would you like to come help me in the kitchen?' This acknowledges their feeling without agreeing with the false perception.

  10. If the person becomes very agitated and your lighting adjustments do not help, consider moving to a smaller room (like a bathroom) with a single soft light source. Smaller spaces feel safer and are easier to keep evenly lit.

What not to do

  • Do NOT turn on a bright overhead light or flashlight beam directly in their face. This creates harsh shadows and can make hallucinations worse. Instead, use soft, indirect light from a lamp or lantern placed low and to the side.

  • Do NOT argue or say 'There is nobody there.' This invalidates their reality and increases fear and confusion. Instead, say 'I know you see something. I am here with you and we are safe.'

  • Do NOT leave them alone in the dark 'to calm down.' Darkness increases disorientation and fear, and they may wander or fall. Stay with them or within earshot, with a soft light on.

  • Do NOT use candles or open flames during an emergency. The flickering light creates moving shadows that can be misinterpreted as people or animals, and it is a fire hazard. Use battery-operated LED candles or lanterns instead.

  • Do NOT try to 'fix' the hallucination by moving furniture or covering mirrors in the middle of the emergency. This adds more change and confusion. Wait until the person is calm and the emergency is over to make environmental adjustments.

  • Do NOT assume that if they are not talking about the hallucination, it has stopped. They may be silently frightened. Watch for signs like staring, pointing, or looking around nervously, and respond with gentle reassurance and light.

Practical tools

  • Soft, Warm Battery Lantern

    A battery-powered lantern with a warm (2700K-3000K) LED bulb, placed on a table or counter, pointing upward. Avoid cool white or blue light, which mimics daylight and can increase agitation. Examples: LuminAID or similar diffused lanterns. Keep one in your emergency kit.

  • Smartphone or Tablet with Calming Video

    Pre-load a video of a fireplace, aquarium, or slow-moving nature scene. Set brightness to medium and place the device across the room. The gentle moving light and sound can distract and soothe. Avoid videos with sudden movements or loud noises.

  • Battery-Operated LED Candles

    Place 2-3 flameless LED candles on a mantle or table. Their soft, warm glow mimics candlelight without the fire risk or flickering shadows. They provide a sense of normalcy and safety. Avoid real candles.

  • Emergency Lighting Kit

    A small bag or box with: a warm LED lantern, a headlamp (for you, not them), a power bank for your phone, a few battery-operated LED candles, and a list of calming phrases. Keep it in an easily accessible place. Test batteries every 3 months.

  • Calming Phrases for the Moment

    Write these on a card and keep it in your emergency kit: 'I am here with you. We are safe.' 'Let me get some light so we can see better.' 'I know you see something. I am with you.' 'Would you like to come sit with me?' Practice saying them in a calm, low voice.

  • Nightlight with Motion Sensor

    Install a warm-toned, motion-sensor nightlight in the hallway and bathroom. During a power outage, if you have a backup battery, plug one in near their bedroom. It provides gentle light when they get up, reducing the chance of a hallucination triggered by sudden darkness.

Discuss with your clinician

Ask the doctor: 'Are there any medications that could help reduce my loved one's hallucinations, especially during stressful times like emergencies? I know antipsychotics are risky for some dementias.'

Ask the doctor: 'Could a cholinesterase inhibitor (like donepezil or rivastigmine) help with hallucinations in my loved one's type of dementia?'

Ask the doctor: 'Are there any non-medication interventions, like light therapy or sensory stimulation, that you recommend for reducing hallucinations at home?'

Ask the doctor: 'If my loved one becomes very agitated during an emergency and I cannot calm them, when should I seek emergency medical help?'

Ask the doctor: 'Could any of my loved one's current medications be contributing to hallucinations? Should we review them?'
