"They wonder how dreams come to be,"
sulked the Sandman ruefully.
"How can it be they don't know me?
I'm famous throughout history.

I take what they watch on TV,
and add some of their memories
and even their desires deep
then sprinkle these on while they sleep."

"What you proclaim is mostly true,"
said the angels as they flew,
"but dreams come not from only you;
the bible will provide the proof.

In sleeping ears, we whisper clues--
grant loved ones gone to visit, too.
We issue peace and fortitude
and chase away those nightmares brewed."

"Who do you angels think you are?"
hissed the demons in the dark,
"to dismiss our evil part
in vexing dreams with our black art?

With our cold touch their peace is marred.
We make them relive all their scars.
Fear, guilt, pain--emotional charge--
ensuring restful sleep is barred."

"You demons do not build the dreams,"
the muses mused with no esteem.
"You only alter them it seems;
but we design the realm of sleep

with inspiration to achieve
which of our talents we bequeath
of voice or body, mind or ink.
We make their dreams reality."

The moral of the story is
that dreams have several origins,
and you with this intelligence
can practice dream analysis.
