"The
echidna [die niet droomt] has a large convoluted prefontal
cortex, larger in relation to the rest of the brain than that of
any other mammal, even humans. I believe it needed this huge
prefrontal cortex to perform a dual function: to react to
incoming information in an appropriate manner based on past
experience and to evaluate and store new information to aid in
future survival. Without theta rhythm during REM sleep, the
echidna would not be able to process information while it slept.
(). For higher capabilities to develop, the prefrontal cortex
would have to become increasingly large - beyond the capacity of
the skull - unless another brain mechanism evolved.
REM sleep could have provided this new mechanism, allowing
memory processing to occur 'off-line'..."

Hartman E. Why do we dream? Scientific American (Feed Your Mind)
2006 (July 14, 2003), with e.g.:
"The
dream appears to be somehow 'connecting up' or 'weaving in' the
new material in the mind"
and conclusion:
"Thus we consider a possible (though certainly not proven)
function of a dream to be weaving new material into the memory
system in a way that both reduces emotional arousal and is
adaptive in helping us cope with further trauma or stressful
events."
