I feel much of the song is about the realization that everything Glass (the main character) understood to be true could just be in his mind. Glass had believed God was speaking to him and letting him know that his life had a greater purpose. This is the the fear induced by self doubt.
I also think there is definitely a dual personality theme. Where the main character has two sides: Zero and Glass. Zero is persona of depression, worthlessness, and despair as characterized by much of the early SP music. Glass is the persona that matches how Billy later was later taking on at this point in his life. I think Billy/Glass came to believe God was speaking to him somehow, and he had a purpose far greater in life. Whether that is true or not, he is questioning his beliefs and that scares him.
I think this song is about his doubts and fears of what he had thought to be an enlightenment, he though he was seeing things as clear as glass, but mostly because life still seems to go on the same depressing way - Zero's persona seems to be creeping back in. To quote the song Zero: "I'm your Zero, I'm the face in your dreams of Glass"
