The song is about Spike's final release. He was a prisoner of his past. When Julia died, it was the final tie to his past. Because he lived in the past, losing Julia was losing his reason to continue.
All Spike had left was to find out if life was just a dream. The only way he could find that out was to die. The only person that could kill Spike was Vicious. The only person that could kill Vicious was Spike. So he went to fight Vicious, to avenge his comrades, and meet his end.
He dies ... and finds out life is just a beautiful dream... and ascends.
