Anyone wake feeling exhausted after seemingly dreaming all night

I never wake refreshed/rested. It has been like this for as long as I can remember and I am 77 now,
My sleep medicine DR called it EPIC dreaming. A rare disorder with no known cause or treatment. His only suggestion was to prescribe Modafinil (a stimulant) taken in the morning to perk me up.
I have tried CPAP and other meds to no avail.
I wonder if this is really that rare.
