One dictionary defines a dream as

1. mental activity, usually an imagined series of events, occurring during sleep.

2. a sequence of imaginative thoughts indulged in while awake; a daydream; or fantasy.

3. a person or thing seen or occurring in a dream

4. a cherished hope; aspiration.

5. a vain hope or imagination

6. a person or thing that is as pleasant or seemingly unreal as a dream.

All of these definitions I esteem.
However much on the subject has not been told
Therefore allow me to be so bold
As it is the Creators desire to truly unfold
The hidden meaning and mysteries
Of dreams and their pleasantries
Certainly there is much more to the matter
Including an element of the divine speaking to man
To empower him all He can
Dreams also affirm what one is to do
As when Joseph had one concerning Mary
Whom he later said I do to
Dreams also forewarn of the future
As did the angel in Josephs dream
At the birth of Christ
By which he and Mary departed into Egypt
To save the babes life.

By the Spirit of God
Daniel interpreted the dream of a king
Then when in a deep sleep himself
Daniel dreamt a hard thing
The dream through Daniel into cogitation
Yet he kept the matter in his heart
Giving himself wholeheartedly to meditation
And that without hesitation

Joseph, the son of Jacob
Was in a dream foretold the future
That he would lead a nation
His ability to discern the meaning of dreams
Saved Egypt and his own people
From devastation

The God of heaven appeared to Solomon
In a dream by night
After which Solomon was given
Outstanding wisdom and intuitive insight

Prior to the crucifixion
Pilates wife was warned in a dream
For God speaks once
Yes twice
Yet man does not perceive it
In a dream, in a vision of the night
When deep sleep falls upon men
In slumberings upon their bed.
Then God opens the ears of men
And seals their instruction
Deep within their unconscious mind
So as to cause them to heed their destiny
And be in line with divine time
Withdrawing from their pride and purposes
With a soul sublime

For dreams are but one attempt by God
To keep mans soul from the pit
To keep his life from perishing
By imparting revelation and inspiration
From which shall come a likely alteration
In thoughts, words and actions
Bringing purification and ultimate transformation
God therefore in dreams
Does show us the future
Dreams being a sign of the great last days
To awake you within
To hear what He is saying
To see what He is doing
Your heart and soul
Hes alluring and wooing.
