A definite answer is still not found. Someresearchers suggest that dreams serve no real purpose, while others believe that dreaming is essential to mental, emotional and physical well-being.The basic idea is as follows: activation patterns are shifting and connections are being made and unmade constantly in our brains, forming the physical basis for our minds. There is a whole continuous sequence in the making of connections that we subsequently experience as mental functioning.Therefore, overall the contemporary theory considers dreaming to be a broad making of connections guided by emotion.
