What is the Scientific Explanation for dreams?

It is suggested that dreaming is a method of sorting information in the brain.

Natural dreams may be stimulated by certain thoughts or emotions, sensations or daily activities (anxiety, one’s physical condition, his occupation, and so forth). (Ecclesiastes 5:3) Research indicates that some dreams are a product of our daily activities, sensations and thoughts. In What Your Dreams Mean, Ann Faraday states that “the majority of dreams in some way reflect what has preoccupied our minds during the previous day or two.” Using electronic gadgetry of the space age, researchers have studied changes in brain waves and the activity in certain brain cells during the dreaming process. Science is still a long way from a comprehensive understanding of dreams, but some conclusions are now quite universally accepted.
