Dreaming prevents psychosis
In a recent survey on dreams, students who were awakened at the beginning of each dream, but had at least 8 hours sleep, had difficulties in concentration, irritation, hallucinations and signs of psychosis after only three days.
When you allow them to sleep more, the brain tries to regain lost sleep and dream time increases.
Dream only what we know
Often dreams are full of strangers who participate in certain parts. Did you know that your brain did not think these people up? They are real faces of real people you've seen in your life, but do not know and do not remember. A vicious killer in the latter may be a dream of a boy who poured petrol into the car of your father when you were a child. We have all seen hundreds of thousands of people in our life, so we have an endless source of characters for our brain, which we use in our dreams.
Not everyone dreams in color
12% of people dream in black and white. The remaining number dream in full color. People also tend to dream of certain topics that are related to school situations, kidnappings, slow running or running on the spot, sexual experiences, frustration, late for meeting someone who is alive, dead but dreaming, falling teeth, flying, exams or a car accident. It is unclear whether dreams related to violence are more emotional for people who dream in color or those in black and white.
Dreams are not what they are
Sometimes we dream something that we can barely associate with. Dreams speak in a deep symbolic language. The brain is trying to compare your dream to something else that is similar. It's like writing to assume and saying that a group of ants were like machines that never stop. But would never compare something to itself, for example, "This beautiful sunset was like a beautiful sunset." So whatever symbol your dream is to use, it is most unlikely to be a symbol of yourself.
Quit smoking and you have more vivid dreams
People who smoked cigarettes for a long time and stopped, have more vivid dreams than before. In addition, according to the journal, Abnormal Psychology: Among the 293 ex-smokers who had quite between 1 and 4 weeks, 33% shared that they have at least 1 dream associated with smoking. In most of their dreams, they got caught smoking and experienced strong negative emotions such as panic and guilt. Dreams related to smoking are a result of denial of tobacco, and 97% of people do not dream while they were still smokers and their occurrence is associated with a remarkable period of withdrawal. They are defined as more vivid than ordinary dreams.
External stimuli capture our dreams
This is called 'incorporation of sleep' It is a feeling that most of us feel when the sound from the surrounding world is heard in the dream. Such an example can be when you are physiologically hungry and you can feeling your brain embedding the hunger in your dream. Surely you had experienced repeatedly drinking a large glass of water in the dream that quenches your thirst and thirst then immediately reappears. When you wake up very thirsty and immediately go to drink water.
You are paralyzed while you sleep
Believe it or not, your body is virtually paralyzed while you sleep, it is most likely to prevent your body to simulate aspects of your dreams. According to a Wikipedia article dreams produce a hormone that helps us to sleep and neurons send signals to the spinal cord which causes the body to rest and later to be paralyzed during sleep.
When you snore, you are not dreaming
Small babies do not dream until they were 3 years old. From that age, children usually have more nightmares until 7 or 8 years old. If you wake up often beyond the period of rotation of the eyes, it is more likely to remember a dream.
