What and How We See, When We Close Our Eyes?

When we close our eyes, we often experience a range of visual phenomena, from simple colors and patterns to more complex images and even hallucinations. These visual experiences can be both intriguing and mysterious and have captured the attention of scientists and philosophers for centuries.

So, what do we see when our eyes are closed? The answer to this question is not straightforward, as the visual experiences that we have when our eyes are closed can be influenced by a number of factors, including our state of mind, our level of sensory deprivation, and our individual brain chemistry.

One of the most common visual experiences that we have when our eyes are closed is the appearance of simple colors and patterns. These visual phenomena are known as phosphenes, and they occur as a result of the stimulation of the retina by pressure or electrical currents. When we close our eyes, the pressure on the retina changes, which can trigger the perception of colors and patterns. These phosphenes can vary in intensity, size, and shape, and can be influenced by a number of factors, including the position of the body, the level of light in the environment, and the level of sensory deprivation.

Another common visual experience that we have when our eyes are closed is the appearance of more complex images and scenes. These images can range from simple shapes and patterns to more complex scenes, landscapes, and even people. These visual experiences are known as closed-eye hallucinations and can be induced by a number of factors, including drugs, meditation, hypnosis, and sleep deprivation. The content of these hallucinations can be influenced by a number of factors, including our individual brain chemistry, our memories, and our emotions.

Finally, when we close our eyes, we may also experience the sensation of being in a different place or environment. This experience is known as a visualized environment, and it can be induced by a number of factors, including imagination, meditation, and hypnosis. The content of these visualized environments can be influenced by a number of factors, including our memories, our emotions, and our beliefs.

In conclusion, the experience of visual phenomena when our eyes are closed is complex and multifaceted, and can be influenced by a range of factors, including our individual brain chemistry, our level of sensory deprivation, and our state of mind. Whether we are experiencing simple phosphenes or more complex hallucinations and visualized environments, the phenomenon of closed-eye visuals remains a fascinating and mysterious aspect of the human experience.
