The gift of night

The most precious and interesting gift night provides us with is the dreams we see in our sleep. It is like movies we see in our minds in our subconsciousness. The movies we see while we are sleeping, the movies produced by our subconsciousness. Though, dreams are rather peculiar phenomenon and so there are several points of view to the origin of dreams.
There is a scientific point of view that explains the fact of seeing dreams. Scientists say that we fall asleep when our brain is too tired and it needs its rest. There are some cells of our brain that function like a safety device. They make us fall asleep when we need to have a rest in order to recover our mental and physical strength.
And the dreams we see when we are sleeping is the messages from our subconsciousness. It is like our brain speaks to us. There are some problems we are ignorant towards, the problems we want to forget, but those problems have to be solved and so our subconsciousness tell us about this necessity. So, we have to recognize those messages in the right way.
But there is also supernatural point of view according to which dreams are recognized as messages from some other worlds. People say that it is a mean for communication with some other worlds, people can't realize when they are conscious. They say it is a foreseeing of our future, they say it is a conversation with our dead ancestors and so on and so forth.
