“Yet more—in some strong passion’s troubled reign, 830
Or when the fever’d blood inflames the brain,
At once the outward and the inward eye
The real object and the fancied spy.
The eye is open, and the sense is true,
And therefore they the outward object view;
But, while the real sense is fix’d on these,
The power within its own creation sees;
And these, when mingled in the mind, create
Those striking visions which our dreamers state;
