At certain moments in history dreams attached to a special, sacred meaning. So, during the Roman Empire, some dreams became the subject of investigation and analysis in the Senate, as were seen as messages from the gods. The interpreters of dreams often accompanied generals in military campaigns, in order to help the rulers see in dreams good or bad omens about the outcome of the battle.
The cultural heritage of the role of dreams is difficult to overestimate, because this topic has become the basis for creating a number of masterpieces of literature, music and painting.
So what is a dream in terms of physiology, and the remarkable process of dreaming?
1. We remember only 10% of our dreams.
Within five minutes after waking up, we have a real chance to "catch its tail" about half of the plot of sleep, but after ten minutes 90% of the content will be lost, and the meaning of the dream fall apart like a house of cards.
2. Blind people have dreams
People who have lost their vision for life, dreaming equal footing with sighted people. People who are blind from birth do not see the images in the usual sense, but just going through different emotions in dreams: the images are formed in their subconscious through smells, sounds and tactile sensations.
3. All sleeping - Dreamers
The complete absence of dreams is a manifestation of some severe mental illness. All normal people, plunging into slumber, dreaming, but most of their waking instantly forgets.
4. In the dream, we only see the real people
Our subconscious mind is not able to independently and randomly generated faces. This means that absolutely all the strangers in your dreams we once saw, but did not remember. It may equally be a man, a year ago, who was riding in front of you with a subway car, or a woman in the background in the through boring episode of the film. Over the lifetime under different circumstances by us are millions of people and, therefore, our brain never experience a shortage of new actors in the most unexpected roles in the scenario of our dreams.
5. Not everyone can see colorful dreams as much as 12% of sighted people see only monochrome dreams. More precisely, it was not until the mid-sixties. Later, the percentage of people who see dreams exclusively in black and white, fell by 4.4% of the total sample of the study. The researchers suggest that the reason for this trend is the ubiquity of color television broadcast.
6. Dreams are symbolic
All probably know the anecdote about Sigmund Freud and his niece: "Sometimes a banana - it's just a banana." But joking aside, dreams can not be interpreted in a straight line, since any object in a dream may be a symbol of another object. Through our subconscious dream speaks to us the language of metaphors and symbols; some of them have global unambiguous interpretation on all continents, others contain only we clear signs.
7. Dreams emotionally painted
Sadly, but the most common emotion experienced by a dream, a longing and despair, and, in general, negative emotions in dreams prevail over the positive.
8. From four to seven
In one night we see four to seven dreams that amount takes from half an hour and two hours.
9. Animals dreaming
According to research conducted on different groups of animals, many of them in a dream experienced similar modes of neural activity. Thinking highly of animal impulses during sleep on the drawing do not differ from men, from which it can be confident conclusion - animals too have dreams, and many of them are going through what he saw at least emotionally, rather than reality.
