They say you dream because your brain is processing everything that has happened throughout your day. You sleep in cycles and one part of the cycle includes R.E.M. Sleep. R.E.M. means "Rapid Eye Movement"-- basically your eyes are moving fast. At this point you are deep enough in your sleep to dream. So you are always dream, it is just that you remember the very last dream you had before you wake.

Answer

It is not known exactly why humans dream but one theory is that dreams represent our subcouncouis.
