Edgar Fawcett - Sleep's Threshold lyrics

What footstep but has wandered free and far Amid that Castle of Sleep whose walls were planned By no terrestrial craft, no human hand, With towers that point to no recorded star? Here sorrows, memories, and remorses are, Roaming the long, dim rooms or galleries grand; Here the lost friends our spirits yet demand Gleam through mysterious door-ways left ajar. But of the uncounted throngs that ever win The halls where Slumber's dusky witcheries rule, Who after wakening, may reveal aright By what phantasmal means he entered in?-- What porch of cloud, what vapory vestibule, What stairway quarried from the mines of night?
