Sleep is Supposed to be.

I started reading some E.D. poetry lately, and it really is perplexing. I'm just wondering if anyone has any thought as to what this poem may mean. If you have any input, it would be much appreciated. Thanks in advance.

SLEEP is supposed to be,
By souls of sanity,
The shutting of the eye.

Sleep is the station grand
Down which on either hand
The hosts of witness stand!

Morn is supposed to be,
By people of degree,
The breaking of the day.

Morning has not occurred!
That shall aurora be
East of eternity;

One with the banner gay,
One in the red array,—
That is the break of day
