Memoirists wish to tell their mind, not their story.
No memoirists writes for long without experiencing an unsettling disbelief about the reliability of memory, a hunch that memory is not, after all, just memory.
Memoirists, unlike fiction writers, do not really want to 'tell a story. ' They want to tell it all - the all of personal experience, of consciousness itself. That includes a story, but also the whole expanding universe of sensation and thought. . . Memoirists wish to tell their mind. Not their story.
I'd like to imagine that "dreamoir" becomes a subgenre of nonfiction, maybe ultimately because I'd love to read many more dreamoirs by other writers - poets and memoirists especially.
