the dream...

Our life is twofold; Sleep hath its own world,
A boundary between the things misnamed
Death and existence: Sleep hath its own world,
And a wide realm of wild reality,
And dreams in their development have breath,
And tears, and tortures, and the touch of joy;
They leave a weight upon our waking thoughts,
They take a weight from off waking toils,
They do divide our being; they become
A portion of ourselves as of our time,
And look like heralds of eternity;
They pass like spirits of the past -they speak
Like sibyls of the future; they have power -
The tyranny of pleasure and of pain;
They make us what we were not -what they will,
And shake us with the vision that's gone by,
The dread of vanished shadows -Are they so?
Is not the past all shadow? -What are they?
Creations of the mind? -The mind can make
Substances, and people planets of its own
With beings brighter than have been, and give
A breath to forms which can outlive all flesh.
I would recall a vision which I dreamed
Perchance in sleep -for in itself a thought,
A slumbering thought, is capable of years,
And curdles a long life into one hour.
