BBC Horizon: Why do we dream ?

Horizon uncovers the secret world of our dreams. In a series of cutting-edge experiments and personal stories, we go in search of the science behind this most enduring mystery and ask: where do dreams come from? Do they have meaning? And ultimately, why do we dream?

What the film reveals is that much of what we thought we knew no longer stands true. Dreams are not simply wild imaginings but play a significant part in all our lives as they have an impact on our memories, the ability to learn, and our mental health. Most surprisingly, we find nightmares, too, are beneficial and may even explain the survival of our species.

REM sleep is one of the most notable qualities of mammals. I think we can credit it very much as one of the contributing characteristics that has led to the intelligence we see in the Mammalian class.

From a psychological perspective, I believe dreams allow is to "resolve" things that we have not/can not resolve in our conscious state. As such, they are a remedy for our mental health and well-being. Even nightmares allow us to release pent-up deep seated emotions (fear, ignorance, stress, frustration, grief, etc.) in a way that, if handled properly, are more healthy than if we did not dream.
