Good thing deathbear is here though, because he could not be any more right! This song makes so much more sense now. It's all about blind faith, thus the "I might be wrong" ties into it. Think about good times with God into heaven, and don't look back at your past. Really, I think Thoms saying, we think we're drifting up into heaven, but, we don't realize that we are about to fall off the edge of a waterfall. We don't know what's at the end of the river (the river is a symbol of life.) We go on through life as we're floating down the river, and getting closer to death. We don't know what happens after we die. We can't swim back upstream and tell others about it, because it's a one-way path. We think at the end of the river is a large lake of eternal life, or something, but its a waterfall to death.

good interpretation, and ive noticed a great deal of allusions to rivers, and journeys in amnesiac, the "muddy river" in like spinning plates, the riveri n pyramid song, the revolving doors in pul/pull revolving doors, the time waiting in packt like sardines, the riding tonight in you and whose army, idk your post just made me think of that, so i dont have many other specifics on the top of my head but im sure a more detailed look would show many more instances
