Lyric discussion by thommy 

He built a glass pyramid on top of the Chelsea, so I think that is somewhat where the "glass room" is coming from...but it also serves as a nice parallel to how public his life was at the time of his career imploding.

I think the song has a lot to do with him reflecting on his career and this alter-ego that the record company and the media help create for him...I hear the last verse as Jobriath (alter-ego or who he was then) deciding to "leave this world behind" or whatever, and the starship stops to pick up Bruce Wayne Campbell (his real self) and take him along, too. The narrator is looking at himself and these different personas/lives that he's been through, and he's ready to just fly away from it all.
