5 An experiment made cats act out their dreams — during REM sleep…
In an experiment, researchers cut the neural pathways that normally disable the body during REM sleep in cats to observe whether they would physically act out their dreams. And just as the researchers had hoped, the cats acted out their dreams physically, even though they were still in REM sleep.

7 We usually forget what we dreamed…
Five minutes after waking up, 50% of a dream is forgotten, and after ten minutes, up to 90% is gone. It’s quite rare for us to remember our dreams in detail, and we typically dream several times per night. [source]
8 Even blind people dream…
People who have never been able to see still dream, but their dream content is different from visual dreams. Instead, their experiences are built on other senses such as smell, sound, and touch. They can also experience strong emotions and vivid emotional impressions, creating a rich and multi-layered dream world without visual input.
In this way, the brain of a blind person works differently when creating these inner experiences, relying on entirely different sensory channels to interpret and process the world during sleep. [source]

9 Why you can’t read in your dreams…
The reason it’s difficult or impossible to read during dream experiences has to do with how the brain is organized. Reading is a complex function controlled by specific regions of the brain, while the visual and emotional experiences of dreaming activate entirely different areas. These regions don’t coordinate in the same way during sleep, which is why text often appears blurry, unclear, or completely meaningless in the dream world. [source]
10 Oneiroid syndrome can make you believe you’re dreaming — even while awake…
There is a real psychological condition called Oneiroid syndrome, which causes people to believe they are in a dream while they are actually awake. It resembles the concept shown in the movie Inception (2010), where Cobb’s wife becomes confused and believes she is still dreaming. [source]

5 Common Questions About Dreams
There is no single answer, but most theories suggest that dreams help with memory processing, emotional regulation, and problem-solving. Many scientists believe dreams are the brain’s way of making sense of thoughts and experiences.
We forget what we dream about because the brain areas responsible for memory formation are less active during REM sleep. Within minutes of waking, 50–90% of a dream fades, making detailed recall rare.
Nightmares are often linked to stress, anxiety, trauma, or sleep deprivation. Certain medications and illnesses can also trigger them. Occasional nightmares are normal, but frequent ones may signal underlying emotional stress.
There is no scientific evidence that dreams can predict future events. However, dreams may feel predictive because they reflect your fears, expectations, or subconscious thoughts, which sometimes align with what later happens.
Most people dream in color, but some report black-and-white dreams — often influenced by media exposure or age. People who grew up watching black-and-white TV report such dreams more often. Dream color is shaped by memory and perception, not eyesight.
