Out of SPACE — out of TIME.
Bottomless vales and boundless floods,
And chasms, and caves, and Titan woods,
With forms that no man can discover
For the tears that drip all over;
Mountains toppling evermore
Into seas without a shore;
Seas that restlessly aspire,
Surging, unto skies of fire;
Lakes that endlessly outspread
Their lone waters — lone and dead, —
Their still waters — still and chilly
With the snows of the lolling lily.
By the lakes that thus outspread
Their lone waters, lone and dead, —
Their sad waters, sad and chilly
Lolling is the action of hanging or drooping in a limp fashion. In this dark dream-land the flowers lack signs of life and do not remain upright 
 
 Lilies have been associated with various representations. They are commonly associated with death and dying but have also been associated with hope, purity and the Virgin Mary. Dreaming about lilies has been said to represent the loss or death of a loved one, a common theme throughout much of Poe’s literature
