Patients with sleep deprivation experience symptoms such as: Visual disturbance (seeing the wrong color, size, depth, or distance) Illusions (trouble identifying common objects and sounds)
Background: Going without sleep for long periods of time can produce a range of experiences, including perceptual distortions and hallucinations.
asleep: With total sleep deprivation, meaning someone hasn't slept at all overnight, hallucinations can start to occur after 24 hours but become more likely when a person is awake for 36 to 48 hours straight.
Sleep hallucinations are imagined events that seem very real. They are mainly visual. They may also involve your senses of sound, touch, taste, and smell. They may even involve a sense of motion.
Prevention strategies
And if there is no underlying medical condition, lifestyle changes may reduce the frequency of hallucinations. Getting enough sleep and avoiding drugs and alcohol can reduce their frequency. If hypnagogic hallucinations cause disrupted sleep or anxiety, a doctor might prescribe medication.
If you're having problems sleeping, you might: be more likely to feel anxious, depressed or suicidal. be more likely to have psychotic episodes – poor sleep can trigger mania, psychosis or paranoia, or make existing symptoms worse.
Hypnagogic hallucinations occur during the hypnagogia stage of sleep, while nightmares generally occur later in the sleep cycle when a person is fully asleep. Generally, vivid dreams, such as nightmares, occur most commonly during the rapid eye movement (REM) stage. View Source of sleep.

Hypnagogic/hypnopompic hallucinations
Hypnagogic hallucinations are vivid and sometimes frightening hallucinations that occur in the setting of sleep onset. These are usually short in duration and the frequency of these events is fairly unpredictable. Hypnopompic hallucinations occur upon awakening from sleep.
Sleep deprivation psychosis refers to experiencing an altered perception of reality caused by a prolonged lack of sleep. Psychosis, in general, refers to an episode in which your brain perceives reality differently than other people in the same situation.
Schizophrenia. Sleep deprivation leads to delusions, hallucinations, and paranoia. In the same way, patients who were awake for 24 hours started to experience symptoms that appeared to be schizophrenia.
A hallucination involves seeing, hearing, smelling or tasting something that doesn't actually exist. Hallucinations can be the result of mental health problems like Alzheimer's disease, dementia or schizophrenia, but also be caused by other things including alcohol or drugs.
Simple visual hallucinations may include flashes or geometric shapes. Complex visual hallucinations may show faces, animals or scenes and may be called 'visions'. Other types of hallucinations include feelings on the skin, smelling or tasting things that cannot be explained.
Auditory (sound) hallucinations: These are the most common type of hallucinations. They involve hearing sounds that aren't real, like music, footsteps or doors banging. Some people hear voices when no one has spoken. The voices may be positive, negative or neutral.
Hypnopompic hallucinations, in particular, are hallucinations that occur as you are waking up in the morning and in a state that falls somewhere between dreaming and being fully awake. View Source . Hypnopompic hallucinations are relatively common, occurring in over 12% of people.
Is insomnia a mental health condition? According to the National Alliance on Mental Illness, it is rare for insomnia to be an isolated medical or mental health condition. Insomnia is usually a symptom of another condition or a result of lifestyle or environmental factors, such as a work schedule or stress.
Anxiety, stress, and depression are some of the most common causes of chronic insomnia. Having difficulty sleeping can also make anxiety, stress, and depression symptoms worse. Other common emotional and psychological causes include anger, worry, grief, bipolar disorder, and trauma.
Sleep deficiency is linked to many chronic health problems, including heart disease, kidney disease, high blood pressure, diabetes, stroke, obesity, and depression. Sleep deficiency is also linked to a higher chance of injury in adults, teens, and children.
When should I go to ER? Sleep deprivation isn't a condition that causes immediate, life-threatening problems, so it doesn't need emergency treatment. However, it can raise the risk of heart attack and stroke, both of which are emergency conditions that need immediate medical care.
