Have you ever wondered if blind people can dream? The answer is yes! Dreams are a mix of images, events, or feelings that we experience in our daily lives. Whether a blind person can see images in their dreams depends on when they lost their vision. If someone became blind later in life, their brain might use visual memories to create dreams. However, if a person has been blind since birth, their dreams are based on sounds, smells, touch, and other sensations they experience every day.
Interestingly, some studies have shown that people who are blind from birth can draw their dreams. This suggests that they might have visual experiences in their dreams, even if they have never seen with their eyes.
For a long time, experts have tried to figure out why we dream, but there is no clear answer yet. One idea, proposed by Sigmund Freud, is that dreams fulfill our wishes and show our hidden desires and thoughts. According to this theory, each image in a dream might have a special meaning.
Another theory, called Threat Simulation, suggests that dreams help us prepare for real-life dangers. For example, nightmares might put us in scary situations, allowing us to practice how we would react, which could be helpful in real life. The Activation-Synthesis theory says that dreams might not have any specific meaning. During the REM (Rapid Eye Movement) stage of sleep, certain brain circuits become active, and as the brain tries to make sense of these signals, dreams are created.
Humans usually dream during the REM stage of sleep. Research shows that animals, like rats, have similar brain activity patterns during their waking moments and REM sleep, suggesting that animals might also dream about their daily activities.
Color blindness, or color deficiency, is a vision issue. Our eyes have special cells called rods and cones. Rods help us see in black and white and do not detect color, while cones help us see colors. There are three types of cones: one for red light, one for green, and one for blue. Together, these cones allow us to see a wide range of colors.
Sometimes, when one or more types of cones do not work properly, it leads to color blindness. This makes it hard for people to tell the difference between certain colors or shades. For example, with red-green color blindness, an apple tree might look different than it does to someone without color blindness.
Keep a dream journal for a week. Each morning, write down any dreams you remember. Pay attention to the senses involved in your dreams, such as sight, sound, or touch. At the end of the week, share your findings with the class and discuss how your dreams might relate to the theories of why we dream.
In groups, choose a dream scenario and role-play it. Consider how a person who is blind from birth might experience this dream using senses other than sight. Present your role-play to the class and explain the sensory details you included.
Use online tools or apps to simulate color blindness. Explore how everyday objects appear differently to someone with color blindness. Create a presentation or poster to share your findings and raise awareness about color blindness.
Research different theories of dream interpretation, such as Freud’s wish-fulfillment theory or the Activation-Synthesis theory. Hold a class debate where each group defends a different theory, using examples from your dream journals to support your arguments.
Investigate how animals dream. Choose an animal and research its sleep patterns and any studies on its dreaming behavior. Present your findings to the class, comparing animal dreams to human dreams and discussing what this might tell us about the purpose of dreaming.

It’s AumSum Time. Can blind people dream? Yes, they dream about various experiences. Dreams are a collection of images, events, or sensations that we see or feel in our daily lives. Whether a blind person can visualize in their dreams depends on when they lost their vision. If they lost their sight later in life, their brain would use visual information stored in their memories to create dreams. However, if an individual has been blind since birth, their dreams would be based on memories of sounds, smells, touch, and other sensations they perceive in their everyday life.
Interestingly, some experiments have shown that individuals who are blind from birth can draw their dreams, suggesting that they not only sense or feel but also have visual experiences in their dreams.
Why do we dream? For centuries, experts have sought to understand the purpose of dreams, but no definitive answer has emerged. One theory proposed by Sigmund Freud suggests that dreams fulfill our wishes and represent our unconscious desires and thoughts. Each image in a dream may hold some meaning, as these thoughts often find expression through dreams.
Another theory, known as Threat Simulation, posits that dreams serve as a defense mechanism. For example, nightmares may place us in threatening situations, allowing us to practice our fight or flight response, which can be beneficial in real-life scenarios. The Activation-Synthesis theory suggests that dreams may not have inherent meaning. During the REM stage of sleep, certain brain circuits activate, and when the brain attempts to make sense of these signals, it results in dreams.
Humans typically dream during the rapid eye movement (REM) stage of sleep. Research has shown that the brain activity patterns of animals, such as rats running for cheese, are similar during both their waking moments and REM sleep, indicating that animals may also dream about their daily activities.
What is color blindness? Color blindness, or color deficiency, is a vision problem. Our eyes contain light-sensitive cells called rods and cones. Rods are responsible for black and white vision and do not detect color, while cones are responsible for color perception. There are three types of cones: one perceives red light, another perceives green, and the third perceives blue. Together, these cones enable us to see the full spectrum of colors. In some cases, when one or more types of cones do not function properly, it leads to color blindness, making it difficult for individuals to distinguish between certain colors or shades. For instance, in red-green color blindness, an apple tree may appear differently.

Dreams – Dreams are stories and images that our minds create while we sleep. – Last night, I had dreams about flying over a city, which made me feel excited when I woke up.
Vision – Vision is the ability to see and interpret the world around us using our eyes. – Good vision is important for reading and recognizing faces.
Brain – The brain is the organ in our head that controls our thoughts, memory, and actions. – The brain helps us solve math problems and remember our friend’s birthday.
Senses – Senses are the ways we perceive the world, such as sight, hearing, taste, touch, and smell. – Our senses help us enjoy a delicious meal by tasting the flavors and smelling the aroma.
Colors – Colors are the different shades we see when light reflects off objects. – The colors of the rainbow include red, orange, yellow, green, blue, indigo, and violet.
Sleep – Sleep is the natural state of rest during which our body and mind recover and recharge. – Getting enough sleep helps us stay focused and energetic during the day.
Animals – Animals are living creatures that can move and react to their environment. – Many animals, like dogs and cats, have keen senses that help them survive in the wild.
Theories – Theories are ideas or explanations that scientists develop to understand how things work. – One of the most famous theories in biology is the theory of evolution by natural selection.
Blindness – Blindness is the inability to see, which can be caused by damage to the eyes or brain. – People with blindness often use their other senses, like touch and hearing, to navigate the world.
Sensations – Sensations are the feelings or experiences we get from our senses, like warmth or cold. – The sensations of the soft blanket made me feel cozy and relaxed.
