Some of our dreams are very strange and don't make sense at all. When we sleep, some areas of our brain are active while others are not. Scientists have proved that the frontal lobes that control emotion, memory, and experiences are active, but the areas that control rational, logical thought are not active at all. Our dreams depend on our emotional state as well. When we are depressed, we usually have dreams which make our sleep disturbed. When we fear something, we may have a nightmare. We can experience intense feelings while sleeping: a sense of exhilaration, joy and excitement or anxiety, trepidation and alarm. The more we think about a person, the more likely we are to dream about him. If we are preoccupied with some problems, we will continue thinking about them while sleeping. That's why the Chinese say, 'What you think during the daytime you will dream at night'.
