Closed-eye hallucinations are related to a scientific process called phosphenes. These occur as a result of the constant activity between neurons in the brain and your vision. Even when your eyes are closed, you can experience phosphenes. At rest, your retina still continues to produce these electrical charges.Sep 18, 2020

Why when I close my eyes I can see images?
What do phosphenes look like? People often describe phosphenes in terms of light even though there’s no light source. Some people say they’re glittery sparkles. Other people describe them as being like stars. Still, others see geometric shapes. What are the most common causes of phosphenes? Many things can cause you to see phosphenes. Sometimes you can see them spontaneously. Possible causes of phosphenes range from rubbing your eyes to neurological diseases or ocular (eye) conditions.
Phosphenes from a blow to the head You may have heard the expression “seeing stars.” If you hit your head or fall, you may see stars — bright flashes of light even when your eyes are closed. This reaction is similar to what you see when you rub your eyes and see light. Pressure on the eyeball can stimulate the retinal photoreceptor cells, causing the light you see.
Can everyone see images when they close their eyes? Some people cannot see anything. Nothing. Their mind’s eye is blank. They experience a neural phenomenon called aphantasia.
Why am I seeing faces in the dark?
Explanations[ edit ] Pareidolia can cause people to interpret random images, or patterns of light and shadow, as faces. [10] A 2009 magnetoencephalography study found that objects perceived as faces evoke an early (165 ms) activation of the fusiform face area at a time and location similar to that evoked by faces, whereas other common objects do not evoke such activation. This activation is similar to a slightly faster time (130 ms) that is seen for images of real faces.
The authors suggest that face perception evoked by face-like objects is a relatively early process, and not a late cognitive reinterpretation phenomenon. [11]
Are phosphenes normal?
However, much more obvious phosphenes can occur in some eye diseases . If what you’re seeing has changed, and the patterns of light become much more noticeable or hang around for longer, it could indicate a problem. For example, bright flashing can be caused by a detached retina, which is where your retina partially comes away from the back of your eyeball, and which needs to be treated as an emergency.
Also, some people get a “visual aura” when they have a particular kind of headache called a migraine. High pressure inside your eyeballs can also cause phosphenes. If what you’re seeing has drastically changed, or you’re worried about what you’re seeing, it’s best to visit your eye care provider, a doctor or an optometrist.
How do I know if I have aphantasia?
Aphantasia is an inability or severely limited ability to create a mental picture in your head. To date, there’s no known cure or treatments that have been proven effective, but research remains in the early stages. The researcher who coined the term aphantasia has called it “a fascinating variation in human experience.” Many people with aphantasia don’t even know they have it until adulthood.
When should I be worried about phosphenes?
Usually, seeing stars is due to temporary pressure on the eye. This is typically harmless and only lasts for a few seconds. However, if you see stars often or they last for a long time, see your provider. You may need treatment for an underlying cause like migraine or a retinal disorder. Frequently Asked Questions If you see stars or sparkles in your vision from time to time and it only lasts a few seconds, it’s probably nothing to worry about.
This often happens after rubbing the eyes or with brief changes in blood pressure. This is due to the effects of orthostatic hypotension, or low blood pressure that occurs when you stand after sitting or lying down. This is common during growth spurts and in thin people with low blood volume. However, it can also be a sign of a serious illness like Parkinson’s disease.15
Are phosphenes caused by anxiety?
Kaleidoscope vision, such as kaleidoscope-like images; pulsing, flashing, wavy, broken, and shimmering lights; phosphenes, and other visual irregularities are common symptoms of anxiety disorder , hyperstimulation , and panic attacks .

What are you supposed to see when you close your eyes?
Try it — close your eye; I’ll wait. Welcome back! What’s the first thing you saw? Most people see splashes of colors and flashes of light on a not-quite-jet-black background when their eyes are closed. It’s a phenomenon called phosphene, and it boils down to this: Our visual system — eyes and brains — don’t shut off when denied light.
What is level 5 closed eye hallucinations? Level 5: Overriding physical perception
This level can be entered from complete sensory deprivation, as experienced in an isolation tank or deep trance of hypnosis, but even there it requires great relaxation. Are you supposed to see things when your eyes are closed? The neurons in our visual system are busily sending signals to the brain via what’s known as the thalamus. So, even when we are in total darkness, just resting our eyes or even when we are asleep, there’s always something to see.
Why do we see black when we close our eyes?
Light comes from a light source The light then hits an object The light then bounces off the object into your eye Your eye sends a signal to your brain. Your brain then figures out what you’re seeing So in order for us to see, you need light getting into your eye (step 3). If you’re in a dark room you have no light source, so no sight (no step 1).
If you shut your eyes, you’re stopping light from getting into your eye (no step 3). When there’s no light getting to your eye, the eye tells this to your brain. So your brain just sees black (the absence of light).
