“Dreams are hallucinations that occur during certain stages of sleep. They are strongest during REM sleep, or the rapid eye movement stage, when you may be less likely to recall your dream. Much is known about the role of sleep in regulating our metabolism, blood pressure, brain function, and other aspects of health. But it’s been harder for researchers to explain the role of dreams.”

How can we separate reality from illusion? What if, to quote from Poe’s poem, ‘All that we see or seem / Is but a dream within a dream’?
One of Poe’s more famous poems, ‘A Dream within a Dream’ muses on the fragility and fleetingness of everything, and asks whether anything we do has any lasting or real effect. As Poe concludes:
O God! Can I not grasp
Them with a tighter clasp?
O God! can I not save
One from the pitiless wave?
Is all that we see or seem
But a dream within a dream?
