I'm slowly drifting to you
The stars and the planets
Are calling me
A billion years away from you
I'm on my way
I'm on...
I'm on...
So I don't think it's about dying. Looking at the album context (Brother and sister kind of communicating through their dreams), this is the first song on the "Brother"-half of the double album. He has desperately been searching for his sister and ended up far, far away from her and therefore is mourning. But in the end, he's leaving to find her. That's my interpretation.
According to the booklet the Lyrics are:
I'm slowly drifting to you The stars and the planets Are calling me A billion years away from you I'm on my way I'm on... I'm on...
