· You forget 90% of your dreams
Within 5 minutes of waking, half of your dream if forgotten. Within 10, 90% is gone.
· Dreams prevent psychosis
In a recent sleep study, students who were awakened at the beginning of each dream, but still allowed their 8 hours of sleep, all experienced difficulty in concentration, irritability, hallucinations, and signs of psychosis after only 3 days. When finally allowed their REM sleep the student’s brains made up for lost time by greatly increasing the percentage of sleep spent in the REM stage.
· Not everyone dreams in colour
A full 12% of sighted people dream exclusively in black and white. The remaining number dream in full color. People also tend to have common themes in dreams, which are situations relating to school, being chased, running slowly/in place, sexual experiences, falling, arriving too late, a person now alive being dead, teeth falling out, flying, failing an examination, or a car accident. It is unknown whether the impact of a dream relating to violence or death is more emotionally charged for a person who dreams in color than one who dreams in black and white. · Dreams are not about what they are about
If you dream about some particular subject it is not often that the dream is about that. Dreams speak in a deeply symbolic language. The unconscious mind tries to compare your dream to something else, which is similar. · Quitters have more vivid dreams
People who have smoked cigarettes for a long time who stop, have reported much more vivid dreams than they would normally experience. Additionally, according to the Journal of Abnormal Psychology: “Among 293 smokers abstinent for between 1 and 4 weeks, 33% reported having at least 1 dream about smoking. In most dreams, subjects caught themselves smoking and felt strong negative emotions, such as panic and guilt. Dreams about smoking were the result of tobacco withdrawal, as 97% of subjects did not have them while smoking and their occurrence was significantly related to the duration of abstinence. They were rated as more vivid than the usual dreams and were as common as most major tobacco withdrawal symptoms.”
· External stimuli invade our dreams
This is called Dream Incorporation and it is the experience that most of us have had where a sound from reality is heard in our dream and incorporated in some way. A similar (though less external) example would be when you are physically thirsty and your mind incorporates that feeling in to your dream. My own experience of this includes repeatedly drinking a large glass of water in the dream which satisfies me, only to find the thirst returning shortly after – this thirst… drink… thirst… loop often recurs until I wake up and have a real drink. The famous painting above (Dream Caused by the Flight of a Bee around a Pomegranate a Second Before Awakening) by Salvador Dali, depicts this concept.
· You are paralyzed whilst you sleep
Believe it or not, your body is virtually paralyzed during your sleep – most likely to prevent your body from acting out aspects of your dreams. According to the Wikipedia article on dreaming, “Glands begin to secrete a hormone that helps induce sleep and neurons send signals to the spinal cord which cause the body to relax and later become essentially paralyzed.”
1. When you are snoring, you are not dreaming.
2. Toddlers do not dream about themselves until around the age of 3. From the same age, children typically have many more nightmares than adults do until age 7 or 8. 3. If you are awakened out of REM (Rapid Eye Movement) sleep, you are more likely to remember your dream in a more vivid way than you would if you woke from a full night sleep.
Gender differences in dreams
Many studies have been conducted to examine differences in the dreams of men and women. It has been shown that women dream of both genders equally, yet 67% of the time the characters in men’s dreams are predominantly male. Women’s dreams tend to last longer and include more emotional content whereas men’s dreams are reported to include more violence, cars, and roads. On average, 8% of people’s dreams include sexual activity. The primary gender difference in sexual dreams is that men tend to dream about unknown or public places and their dreams often feature strangers, while the opposite is true for the majority of women. Women more often dream of enclosed bodies of water, such as pools, lakes, ponds. Of course this data is based on general percentages and is not true for everyone.
Your brain is active when you dream
Studies have provided evidence suggesting tremendous variation in brain activity during sleep. This has been demonstrated using EEG technology. Scientists have identified five distinct stages of sleep, characterized by differences in brain activity. Stages 1-4 and a final stage labeled rapid eye movement (REM) sleep. When awakened during REM sleep, subjects report dreaming. With the development of new brain imaging technology in the early 1990’s we learned even more about brain activity during REM sleep. Researchers found that certain areas of the brain are extremely active during the REM sleep state, even more active than being awake. Studies have shown that certain visual areas of the human cortex, which decode complex visual scenes, are significantly more active during REM sleep. Intense activity is also observed in the limbic system, which is a set of structures heavily involved in human emotion.
Adults dream off and on, for a total of about an hour and half to three hours every night.
