About a dream

Almost third of life people spend "dream" in a dream. Every evening during habitual time us starts to drive at a dream. At seven or eight o'clock (and some – on five or six) we are disconnected from an external world and we leave in silent dialogue with ourselves. Human mind has initially been created inquisitive, and people pondered, the dream why in a dream mysterious dreams come what for is necessary.

in a dream we spend third of life. It is counted up, that the person at the age of 72 years has on the to the account of an order of 210 000 hours of a dream.

the dream is necessary to the person that its body has had a rest, however our brain in a dream continues to work tensely.

Scientists had been allocated four phases.

for the first phase the general relaxation and radiation by a brain of ALPHA WAVES is characteristic; thus eyeballs make slow circular movements. The person passes in this phase through the CONSCIOUSNESS gate to SUBCONSCIOUSNESS. Muscles relax, heart beat is slowed down. In the first phase the sleeping has a sensation of that he has a dream, but thus it is easy for waking; having woken up, it can deny, that slept. But if sleeping not to disturb, it will gradually pass in the second phase of a dream.

on to the second phase the brain generates BETA WAVES, and it is reflected at once on энцефалограмме. Slow rotary movements of an eyeball proceed, but all dreamt at the given stage and the majority of cases is forgotten at awakening. After 20-30 minutes of stay in the second phase the sleeping passes to the following phase of a dream.

In to the third phase frequency of radiation of brain waves sleeping considerably goes down in comparison with activity of alpha waves in a wakefulness condition. On this phase to wake sleeping much more difficult as muscles become more weakened, heart beat decreases, a body temperature decrease, the blood pressure falls.

the fourth phase on энцефалограмме is characterised высокоамплитудными and the low-frequency waves, named DELTA-WAVES. The phase comes approximately in thirty minutes after засыпания. It is a phase of the deepest dream - it is possible to name it an oblivion stage. Having stayed in this phase 20 minute the sleeping comes back to a superficial dream. During this moment detail of brain waves on the indicators is similar their activity in the first phase, but thus sleeping very difficultly to wake. Sleeping comes back in the first phase, but it differs from an initial phase of a dream a little. It is a so-called BGD-PHASE (БГД – fast movement of eyes). Most often accurate dreams visit us at the given stage. After 10-20 minutes in phase БГД sleeping again passes through all phases set forth above. Such cycles can repeat many times within night.
