What does this poem mean?

Question

i just cant understand this verse??

Take this kiss upon the brow!

And, in parting from you now,

Thus much let me avow--

You 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 the less gone?

All that we see or seem

Is but a dream within a dream
