Take this kiss upon the brow!
And, in parting from you now,
Thus much let me avow-
Your are not wrong, who deem
That my days have been a dream;
Yet if hope has flown away
In a night or in a day,
In a vision, or in none,
Is it therefore less gone?
All that we see or seem
Is but a dream within a dream...

- -Edgar Allen Poe "A Dream Within A Dream"
