I love your title for this poem. It's perfect. Very evocative.
The poem itself doesn't disappoint either.
Just a couple of things that could improve it maybe. The fourth line of the second stanza doesn't fit the rest of the rhyming scheme. Perhaps "Is not really here" instead of "Just isn't real" would be better? And the rhythm in a couple of places could be improved with only slight alteration.
But these a just quibbles. I really enjoyed it.
