Did you dream about something last night? Nice dream, or nightmare? Many people say that dreams mean something. But most of our dreams mean nothing. We usually dream every night in our sleep, but we forget it when we awake. Sometimes, we remember the dream, but it’s not clear.
How could we dream in our sleep?
A theory says that sleep is a state of exhaustion, requiring restoration of bodily functionality. However, our brain never sleeps. It keeps working all the time. Dreaming means that the brain is not switched off.
Sleep is an almost similar situation with coma, we are in unconscious condition. We are not aware of ordinary sound around us and we don’t know if someone or something is touching or watching us. So, we have to wake up and reach the conscious condition anytime.
For example, someone calls your name, your alarm rings or maybe a crocodile suddenly comes to eat you. You have to wake up to consciousness to respond to those things. It’s ok that you keep sleeping when your friend is calling you, but you put your life in danger if you don’t aware that a crocodile is biting your feet
Why we dream?
The function of dreaming is keeping our brain working so that we don’t fall to a deep coma. We don’t shut off an automobile engine if we anticipated its use in the near future. Therefore, we allow an automobile engine to idle, to let it tick over very slowly, ready for instant acceleration.
One night, someone dreamed about crying baby that really disturbed her. When she woke up, she relized that swans were roaring behind the house. This is one of example that our brain keep responding our sorrounding.
Because of the function of dreaming, animal must be dreaming too in their sleep. They need to always be aware of any danger around them and keep themselves safe.
