What's in a Dream?

It's author's perception and curiosity of what dream is and what others define it.

Dream---a reality or fantasy?
A short word yet a mystery
An array of lights one can see,
A shadow of truth in the deepest sea,
A marvel of sounds one can hear---
Or a memory that one can't bear,
Sometimes in a dream God intervenes
Wherein one sees ahead of time,
And one glances at the past behind,
Then what's in a dream?
Is it magical, a warning, or such a divine,
Whatever a dream is to be---
It touches the mind, body, and soul within thee.
