Dreamscapes, Dali and Surrealism, too #1

And what is this-
the stuff of dreams?
Is it a gateway 
to the subconscious,
as we've been told
or merely a jumbling
of thoughts and images
some undecipherable,
nocturnal unraveling
of the mind, the self?
Is it a frenzied flight
of fancy,
often quasi-realistic?
And as for me, myself,
dreaming I have
flown
soaring and suspended
and I've also reversed time,
journeyed through borderless
dimensions
of Heavens and hells.
I've attained wealth,
seen wars
and struggled for peace.
I've visited exotic locales
some terrestial
others not...
and I've found 
what I lost
spoken with the dead,
those
dear ones departed.
Awake,
this would be deemed
delirium,
a dangerous psychosis.
But in sleep,
eyelids fluttering
dreaming 
is natural and necessary.
Even dogs dream
paddling their feet,
twitching
occasionally.
And I wonder
are dreams truly
a wish
that the heart makes?
But then, what of
nightmares?...
Or is this all
like a running reel
of our hopes and fears
worries and wishes
triumphs and terrors?
Is this dreaming
some sort of pschological
confetti?
a melange of
memory-
just another
of the brain's
many, mysterious marvels?
