Can aliens sleep?
This question is wrong. Thus, the proper question is: Should aliens sleep?
While they are able to close their eyes and dream like most, there is no resting. Aliens will wake up and be just as fatigued as they were before sleeping.
So then, should aliens sleep?
No. They should never give slumber to their eyelids, nor should they cease from their objective pursuit. The life they so want with all their heart can only be obtained through endless seeking.
The lands of Absolute Elsewhere is a place that draws the aliens, binds them to a distant comfort, and opens its mystical arms to gather its sleep-deprived inhabitants towards the homely gates.
Though there may not be any real sleep, there is a certain rest an alien can presently perceive. It is to remove the hardened mask of alienation between them and others; though, having yet to find the truth about their existence, they are forced to adapt should their kind be exposed.
And when learning to adapt outside of themselves, no longer holding on within, an alien’s internal visage is strengthened. This balancing act, between looking within and living without, is the only rest aliens can find in their lifetime outside of Absolute Elsewhere.
Where in those starry lands of Elsewhere exist bountiful expressions of otherworldly emanations, primed to deliver each voyaged alien to their own reward.
These are the sensual mysteries of Absolute Elsewhere.
