Fragment: 'Is It That in Some Brighter Sphere'

Published by Dr. Garnett, "Relics of Shelley", 1862.

 Is it that in some brighter sphere We part from friends we meet with here? Or do we see the Future pass Over the Present's dusky glass? Or what is that that makes us seem  To patch up fragments of a dream, Part of which comes true, and part Beats and trembles in the heart?
