Respond to visual hallucinations by staying calm, reducing sensory stimulation, and seeking medical evaluation if they persist or cause distress.
Can you have physical hallucinations?
Yes, physical hallucinations—also called tactile hallucinations—are real perceptual experiences where you feel touch, pressure, or movement on your body when no external stimulus exists
These sensations might include crawling, tingling, or the feeling of being touched. They’re often tied to medical conditions like neuropathy, substance use, or psychiatric disorders such as schizophrenia or delirium.1 According to the Mayo Clinic, they can also stem from medication side effects or neurological conditions like Parkinson’s disease or stroke.2 If these sensations stick around, it’s worth checking in with a healthcare pro to figure out what’s behind them.

Can you touch visual hallucinations?
No, you cannot physically touch visual hallucinations, because they exist only in perception and have no physical form
Visual hallucinations are images, patterns, or scenes that appear real to you but aren’t actually there—like seeing people, animals, or detailed landscapes no one else notices.3 While they might feel emotionally real, you can’t interact with them physically. Healthline points out these hallucinations often pop up with eye disease, neurological issues, or psychiatric conditions.4 If they’re happening a lot or bothering you, it’s smart to get them checked out. Understanding how to process visual information can help clarify these experiences—learn more about the stages of visual information processing.
How do you tell if you are hallucinating?
Hallucinations are characterized by perceiving sensations that others do not experience—such as seeing lights or objects, hearing voices or sounds, or feeling unexplained touch
The National Institute of Mental Health (NIMH) suggests asking yourself if these perceptions happen when you’re fully alert and can’t be explained by your surroundings.5 They might include vivid images, sounds, smells, tastes, or physical sensations. If they come with confusion, disorientation, or trouble functioning, they could signal a medical or psychiatric emergency and need quick attention.

What triggers hallucinations?
Hallucinations can be triggered by substance use (e.g., alcohol, LSD, cocaine), withdrawal, delirium, dementia, neurological disorders, medications, sleep deprivation, or severe anxiety
The Mayo Clinic notes that conditions like Parkinson’s disease, epilepsy, and brain tumors can also spark hallucinations.6 Medications with psychoactive effects—like anticholinergics, opioids, or corticosteroids—are another common culprit. Environmental factors, such as sleep deprivation or extreme stress, can lower your threshold for hallucinations, especially if you’re already vulnerable.7
What is Charles Bonnet syndrome?
Charles Bonnet syndrome (CBS) is a condition in which people with deteriorating vision experience vivid, complex visual hallucinations while remaining fully aware that the images are not real
These hallucinations often feature people, animals, or detailed scenes and can feel pleasant or neutral.8 CBS happens because reduced visual input to the brain can trigger spontaneous neural activity that the brain misinterprets as real images. It’s not a mental illness and doesn’t mean cognitive decline is happening.9 The NHS stresses that these hallucinations are purely visual—no sound, smell, or touch involved. If you’re exploring creative ways to present information, you might find techniques of visual merchandising interesting.
What are the 5 types of hallucinations?
The five main types of hallucinations are: visual, auditory, olfactory (smell), gustatory (taste), and tactile (touch)
Each type corresponds to a different sensory channel where something feels real but isn’t. Auditory hallucinations—like hearing voices or music—are the most common in psychiatric conditions such as schizophrenia, while visual and olfactory hallucinations often stem from neurological or medical causes.11 The American Psychiatric Association adds that even healthy people can experience hallucinations during sleep deprivation or sensory isolation.12
Can hallucinations go away?
Yes, many hallucinations—especially those caused by substance use, sleep deprivation, or temporary medical conditions—can resolve on their own once the underlying trigger is addressed
For instance, hallucinations tied to alcohol withdrawal or certain medications often fade as the body stabilizes.14 But if they stick around or get worse—especially with confusion or behavioral changes—it’s time to see a doctor. Conditions like dementia, psychosis, or neurological disease could be at play, and early intervention makes a big difference.

What do visual hallucinations feel like?
Visual hallucinations can feel like seeing lights, patterns, shapes, or even complex scenes that aren’t really there, often without accompanying sound or physical sensation
These experiences might range from simple flashes or geometric designs to lifelike images of people or places.16 People on psychedelics often describe them as vivid and emotionally intense, while those with Charles Bonnet syndrome might find them neutral or even pleasant.17 Harvard Health points out that how clear and complex they feel depends entirely on the cause. Understanding how sensory input reaches the brain can provide context—read more about sensory input to the brain.
How do you stop hallucinations?
Stopping hallucinations usually involves treating the underlying cause—such as adjusting medications, managing substance use, improving sleep, or addressing neurological or psychiatric conditions
In some cases, antipsychotic meds might be used to dial down disturbing hallucinations.19 Lifestyle tweaks—like cutting back on caffeine and alcohol, fixing sleep habits, and managing stress—can also help.20 Just don’t try to self-manage without a doctor’s input—some causes need urgent care.
Can anxiety cause hallucinations at night?
Yes, severe anxiety—especially when it disrupts sleep—can lead to hypnagogic or hypnopompic hallucinations, which occur during sleep transitions
These might include hearing voices, seeing shadows, or feeling a presence—and they’re usually short-lived.21 The Anxiety and Depression Association of America (ADAA) says they’re more likely during high-stress periods or when sleep is poor.22 Relaxation techniques and better sleep routines can often reduce how often they happen. If you're preparing for a high-pressure situation, learning how to respond to interview feedback might help manage stress.
How do you stop musical hallucinations?
There is no universally effective cure for musical hallucinations, but treatments like dopamine-modulating medications, antidepressants, or anticonvulsants have helped some individuals reduce symptom severity
Musical hallucinations—often involving repetitive songs or melodies—are usually tied to hearing loss, brain injury, or neurological conditions.23 A 2023 study in PMC found that combining medication with cognitive behavioral therapy eased distress for some patients.24 If these hallucinations are bothersome, a neurologist or ENT specialist can help.
Who gets Charles Bonnet syndrome?
Charles Bonnet syndrome most commonly affects older adults with significant vision loss, especially those aged 80 and above, though it can occur at any age with any level of visual impairment
The National Eye Institute (NEI) says people with macular degeneration, glaucoma, or diabetic retinopathy are at higher risk.25 CBS doesn’t mean eye disease is worsening and can even show up with mild vision loss.26 It’s key to tell CBS apart from psychiatric hallucinations, since they’re managed differently.
How common is Charles Bonnet?
Charles Bonnet syndrome is estimated to affect about 10–20% of people with significant vision loss, making it relatively common despite low public awareness
The BrightFocus Foundation notes that many people never mention their symptoms because they’re afraid of being mistaken for dementia.27 Awareness is growing, but underreporting still makes it harder to get the right help. Spotting CBS early lets people understand their condition and find support.
Why am I seeing things in my peripheral vision?
Peripheral flashes or flickering lights are often caused by posterior vitreous detachment—a normal aging process where the gel-like vitreous inside the eye pulls away from the retina
This tugging can stimulate the retina, creating the illusion of flashing lights or arcs, especially in dim lighting.28 These flashes are usually harmless but should be checked by an eye doctor to rule out retinal tears or detachment, which need quick care.29 The American Academy of Ophthalmology (AAO) advises getting checked right away if flashes come with new floaters or vision loss.30
What are the two most common hallucinations?
In clinical populations, auditory hallucinations are the most common, followed closely by visual hallucinations
These two types show up most often in conditions like schizophrenia, bipolar disorder, and major depressive disorder with psychotic features.31 The American Psychiatric Association adds that olfactory and tactile hallucinations are less common but can still pop up in neurological or medical cases.32 Getting the diagnosis right means figuring out if the cause is psychiatric or organic.
