Brain waves

Scientifically, dreams visit us in a stage of sleep called, R.E.M., characterized by rapid eye movements, increased breathing rates and increased brain activity, suggesting that dreams may be snippets of memories that we have deep in the past mixed with more recent ones that have been activated during this stage.

But why do we dream?

Oneirology

Oneirology, also known as the study of dreams, looks deep into the human psyche and seeks to explain the meaning of dreams.

It is suggested that dreams are manifestations of our subconscious desires and unsolved problems that lie hidden deep inside the darkest parts of our minds.
