Trapped In A Magical Painting Poem by Ace Of Black Hearts

An image drawn.
A picture to capture world.
Once inside there is no way out.
The magical door that only opens from one side.
Disappearances with what is thought to be insight and vision.
But only if you knew, it is a creature all its own.
Ensnaring and enslaving its victims at random.
Colors never seen from the alternate dimension.
A portrait hanging upon the wall.
Prisoners passed by everyday on the way down the hall.
Screaming but no sounds come out.
How it was made is not truly known.
It is older then the time of our recorded age.
Some knowledge has been forgotten.
Some things of have not been passed on.
Tell me are any people you see in this painting recently added?
Where have there poor souls or bodies really gone?
Are they happy in the world in which they have become lost?
Tell me is the moon rising, or is it again portraying another dawn?
