For the majority, insomnia is a concept related to the inability to sleep or to sustain sleep, and a few people know how profound insomnia’s impact may be after it lasts for some time. Perhaps the most shocking and disturbing consequence of chronic insomnia is the illusion a person sees something that is not there. People who wake up suddenly after sleeping for many nights in a row and think they see things moving in the dark or hear sounds that aren’t there are experiencing the frightening effect of insomnia.
This is a comprehensive blog on the central question does insomnia cause hallucinations or not? Can insomnia cause hallucinations? Hallucinations due to lack of sleep, What exactly insomnia hallucinations are, can lack of sleep cause hallucinations or not, the causes of the occurrence of insomnia hallucinations, and how to cope with them.
What Are Insomnia Hallucinations?
The Hallucinations associated with insomnia are visual, auditory, or tactile perceptions, which do not derive from actual external stimuli. Generally, individuals suffering from these illusions may see things or objects that are not real, hear voices, or feel some things that do not exist. These manifestations can be weak, for instance, perceiving geometric patterns or low-pitched sounds, and they can be more robust, for example, seeing natural objects or persons that do not exist.

While hallucinations are most often triggered by mental illnesses or drug abuse, one of the biggest causes is lack of sleep. These perceptual distortions become worse the longer the person is without sleep, in any case.
Types of Insomnia Hallucinations:
- Visual Hallucinations: These include shadow forms, shapes, or bright lights. Others may also see precise figures, such as human and animal figures or objects that do not exist.
- Hallucinations of auditory type: This includes the experience of hearing voices, music, or indistinct sounds. These can be usually quiet noises, but sometimes, they can also be loud noises that are hard to ignore.
- Tactile Hallucinations: Much rarer but troubling tactile hallucinations occur when a person feels something not there on their skin. Some people reported an itchy feeling, such as bugs crawling or touching the skin.
- Olfactory Hallucinations: include pictures in mind coming with olfactory touches, such as seeing smoke, flowers, or even foul odor when there is none.
Why Does Insomnia Cause Hallucinations?
Hallucinations caused by insomnia happen because the brain is trying to sleep. Sleep is critical to helping the brain store information, reform memories, and regulate cognitive and emotional well-being. As the brain behaves erratically without sleep, one of the first functional areas to suffer a loss of functioning is the part of the brain that determines reality and fantasy.
Sleep Deprivation and Cognitive Decline
The ability to focus, process incoming information, and store it further also slows down when the person has had little sleep. This cognitive decline causes the brain to give wrong signals where there are no stimuli, hence the hallucinations. Usually, the brain sorts stimuli and decides what is real and fake. Nevertheless, in a state when you have not slept, the brain fails to perform this function properly and causes psychosis.
- REM Sleep Deprivation
Some people think that people who have hallucinations caused by insomnia don’t get enough REM sleep. REM sleep is when our brains dream and remember things. If we don’t get enough REM sleep, our brains might start dreaming while awake and lose touch with reality.
- Microsleeps
When we have not slept for a long time, the brain can experience microsleeps, when some part of the brain is awake while the other shuts down for a few seconds. It was found that during microsleeps, the brain may temporarily enter a dreaming state, contributing to sudden hallucinations. These are said to occur in intervals as short as one or two seconds; however, they last long enough to cause hallucinations.

The Science Behind It: How Sleep Affects Perception
For the human brain to be able to interpret the sensory information it receives, breathing, restoration of the sensory organs, and sleep are critical. When we don’t sleep well, our cortex, the part of the brain that deals with decision-making processes, focus, and emotions, is not functioning correctly. Occasionally, the occipital lobe that deals with vision can be affected and lead to fire, which can cause vision. Moreover, the brain region dealing with sounds can become hyper-sensitive to noise, causing even the soft sounds to be perceived as louder. Other mental illnesses like anxiety, Schizophrenia, psychosis, depression, or bipolar disorders can alterations in sleep patterns and therefore cause hallucinations.
When these systems get interfered with by a lack of sleep, the brain is no longer capable of regulating background noise, and patients get hallucinations.
Who is at Risk of Insomnia Hallucinations?
Anyone can experience hallucinations after prolonged sleep deprivation, but certain groups are more at risk, including:
- Chronic insomniacs: People experiencing chronic insomnia are more likely to have hallucinations compared with people with occasional problems with sleep.
- Shift workers: Night shift or any other interrupted and irregular working schedule decreases people’s productivity due to sleep loss and may result in hallucinations.
- Students or professionals pulling all-nighters: Hallucinations may likely occur due to long hours of concentration and inadequate rest during study, before examinations, or during shifts in the workplace.
Preventing and Managing Insomnia Hallucinations
The following are some of the most effective steps to cope with insomnia hallucinations:
- Insomnia hallucinations; prevention and control
It’s well-known how disturbing hallucinations resulting from insomnia can be; if you have ever had some, you will surely know this. Fortunately, there are steps you can take to manage and prevent these episodes:
- Prioritize Sleep Hygiene
Eradicating sleep disorders requires following the proper sleep hygiene practices as the first step to fighting insomnia. Make it a habit to try to get to bed and rise simultaneously. Reduce your caffeine intake, avoid using screens just before going to bed, and ensure your room is dark and free from noise.
- Manage Stress and Anxiety
Most people’s causes of insomnia are stress and anxiety. Coping techniques include mindfulness, meditation, deep breathing, or journaling before bed. If stress is a factor, you should try to include some relaxation in your evening regimen.
- Seek Medical Help
A doctor or a healthcare provider should deal with insomnia or hallucinations. You might have other conditions that present themselves as insomnia, such as sleep apnea or a mental disorder. CBT-I is a non-pharmacological treatment scientifically accredited for helping patients retrain their brains about sleep.
- Medication
In some cases, people should use sleeping pills, which are available without a prescription, and or should seek a doctor’s advice for them to get some sleeping pills. But these should be taken carefully and under the instructions of a doctor, as some sleeping medications lead to side effects or dependency.
- Limit All-Nighters
When one feels they have so much to do and can work all night, they end up yawning all day and hallucinating at night. If your working schedule or studying requires you to work at night, you should try to get some night’s rest to avoid complete exhaustion of your brain.
