Read the text and answer the question. More than one answer may be correct. - вопрос №1897849
We spend about one-third of our lives sleeping, and when not dreaming, we аге completely without consciousness. Even the humble fruit fly sleeps while some creatures, such as dolphins, sleep with half their brain at а time. Sleep matters: go one night without it and we suffer the next day; go too long and we would die. As we fall asleep, the rapid electrical activity found in normal waking fades away and slow, deep waves start coursing throughout the cortex. Most sensory input is blocked and nerve signals to muscles are interrupted, preventing us from acting out our dreams. Despite this, the brain remains almost as active as when we are awake. Sleep is usually divided into three stages of increasing depth, plus the «rapid eye movement» (REM) stage in which brain activity is similar to waking and most dreams occur. There are many theories about why we sleep. Some researchers think sleep helps consolidate memories from the previous day.

1) Critical perception of uncommon situations is reduced.2) Concept of personality becomes diluted.3) A dreamer lacks the free will.4) Control of peristaltic activity is lost.5) Dreams that occur in the “slow wave” stage are static.6) Dreamer experiences connection to dolphins and fruit flies.
