Hypnogogic hallucinations are brief hallucinations that take place as you're falling asleep. They're common and usually nothing to worry about. They're usually visual in nature, such as images of patterns, shapes or flashing lights.
Some people have hallucinations as they're waking up. These are called hypnopompic hallucinations. These types of hallucinations are similar to hypnagogic hallucinations, but they may feel more like an extension of a dream. Sleep paralysis is often associated with hypnopompic hallucinations.
These hallucinations can be the result of narcolepsy, a condition that causes people to fall asleep suddenly. The rapid descent into REM sleep may be a factor in hypnagogic hallucinations. Aside from narcolepsy , hypnagogic hallucinations may have links with Parkinson's disease and schizophrenia .
Hallucinations are not among the more common symptoms of anxiety disorders. But they can occur in people who have various types of anxiety. A study in the January 2016 edition of the journal Consciousness and Cognition documented a connection between anxiety and auditory hallucinations.
People who experience hallucinations do not necessarily suffer from a mental illness. It is quite common for people in the general population to experience passing and infrequent episodes of hallucination, and many people recover completely.
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. Experiencing hallucinations can be confusing and can cause significant distress, so it's important that you seek help as soon as you can.
Examples include a sensation of impending threat, feelings of suffocation, and sensations of floating, spinning, or falling.
Yes, stress is a common cause of hallucinations because of how stress affects the nervous system, sensory systems, and brain function. Since anxiety stresses the body, anxiety can also cause hallucinations. Many anxious and stressed people hallucinate, including auditory, visual, and olfactory hallucinations.
Hallucinations can occur with sleep onset (hypnagogic) or at the end of sleep (hypnopompic). Such hallucinations may include visual, auditory, or tactile components and may last seconds to minutes.
Long periods without sleep are associated with cognitive difficulties, and can produce psychological symptoms ranging from mood changes to psychotic experiences such as hallucinations (3, 4).
Pareidolia is a psychological phenomenon that causes people to see patterns in a random stimulus. This often leads to people assigning human characteristics to objects. Usually this is simplified to people seeing faces in objects where there isn't one.
But have you ever had a dream with a person in it whom you have never seen before in your life? It may seem that way, but it is impossible. It is believed that the human brain is incapable of “creating” a new face.
Typically, illusion in schizophrenia patients include people, faces, animals, objects with frightening content (26–28). Like schizophrenia, patients with bipolar disorder also show visual illusion (29, 30).
People commonly see moving patterns and shapes, or vivid images of faces, animals, or scenes. Up to 35% of hypnagogic hallucinations involve hearing sounds, such as voices or music. In 25% to 44% of cases, a person experiencing a hypnagogic hallucination feels a physical sensation, like falling or weightlessness.
“Felt presence” is a phenomenon where you feel that someone or some entity is near you, sometimes accompanied by an actual hallucination of some form. The phenomenon occurs in sleep paralysis (see this blog post) but also in certain neurological conditions. It can even be induced in healthy people while they're awake.
What Causes a Sleep Paralysis Demon? Although the exact cause of sleep-related hallucinations remains unknown, many experts believe that hallucinations during sleep paralysis occur when people experience the vivid dreams of REM sleep while they are awake.
Tactile hallucination is the experience of feeling like you're being touched when you're not. It's one of the most common aspects of sleep paralysis. Many people say they feel pressure or contact. It's like something or someone is holding them down.
Hypnopompic hallucinations typically occur as you're waking up. They're mostly visual, and may feel as if your dream state is continuing into your wakefulness, as with lucid dreaming. Hypnagogic hallucinations are similar but more often occur as you're falling asleep.
Hypnopompic Hallucinations. Vivid dreamlike experiences—called hypnagogic or hypnopompic hallucinations—can seem real and are often frightening. They may be mistaken for nightmares, and they can occur while falling asleep (hypnagogic) or waking up (hypnopompic).
If you have a vision of someone in a particular situation, you imagine them in that situation, for example because you are worried that it might happen, or hope that it will happen.

It's usually because your brain is trying to work things out and fix your feelings for a certain person in your life. This can be a way for you to learn more about the person, see what they've been doing, or figure out how things went sour between the two of you.
