"virtually everybody has at least four dream periods a night. they occur at the approximate rate of one every ninety minutes. the dream periods start out as short, about ten minutes or less, and end up in the morning considerably longer and sometimes lasting half an hour or more. this last dream is generally the one we tend to remember in the morning and is liable to be more elaborate than the earlier dreams. of the many variables affecting dreaming, age has perhaps the strongest effect. studies of newborn children have shown that they spend about seventy percent of their sleeping time in REM (rapid eye movement) sleep, while adults dream only about twenty percent of their sleeping time. as old age approaches, this percent diminishes even further."
soon i'll explain REMs in more detail.

depressing, i was hoping the percentage would get higher with age
and we only have dreams during rem sleep?
that is sort of depressing.
