Going away from the abstract Ziltoid story, I feel like this song is about something that you enjoy, but isn't doing you any good in the long run. A good example would be drugs, and I also think the lyrics fit that theme the best.
The first lines seem to be about how you don't want the moments to end when you are high and how much they seem to open up your mind ("Explain to me, infinity"). I know that many artists are using drugs because they believe to write better songs with them, and those lines sum that behavior up quite good I think.
Nevertheless, it's over sooner or later and you might even and up worse than before, hence the "yet so vulnerable" line.
