how is the realtion of mental illness and dream?

anyone lives in dream,
human has dreamed every night.
night make us travel into dreamnight.
we human do many thing in dream.
but, in the morning, we wake and forget everthing of last night.
like this, dream isn't real but unreal reality.
we human shouldn't mistake dream for reality.
that is both sides of dream, reality or imaginary.
by Shopehauer, "dream is the madness of short time, madness is long dream."
but, dream is the rich happiness offerring to people to suffer body and mental illness the thing which reality deny.
Kant said, fanatic is the person dreaming eye-opened.
another, madness is the dream of in awaken of sense.
in other words,
the combination of complicated thought and weakness of judgement prescribed dream and madness entirely.
as it were,
seeing in cold brain,
the heavy value of self mental various ability being thought outstanding has discovered in mental illness or dream.

Moon,
lead into deep night,
dream and live in comfort sleep.
for better day..
