Why should we hurry why indeed — Nightmare

Why should we hurry-why indeed? 1
When every way we fly
We are molested equally
By immortality.
No respite from the inference
That this which is begun,
Though where its labors lie
A bland uncertainty
Besets the sight
This mighty night-
(F.1683/J.1646)

[5] inference:: a situation that is inferred; a dream may be an inference of one's mind.
