“We all are living in a dream, but life ain’t what it seems, oh everything’s a mess.” This is when he realizes that we have a false perception on life, and that things are crazy. “And all the sorrow I have seen” The singer is basically seeing everything that’s going wrong in the world. “But I want to dream, I wanna dream, leave me to dream.” He or she doesn’t want to see this stuff. “In the eyes, of a teenage crystallized, oh the prettiest of lights that hang the hallways of this home.” I think he mentioning the suicide of teenagers, and the “crystallized” are the faces that they last made. “And the cries, from the strangers out at night, they don’t keep us up at night, we have the curtains drawn and closed.” This goes back to the person not wanting to see all the bad stuff, or they just want to be ignorant to the crime, which i believe is what the cries are, murder and all that crap. This is what I believe the song means, but this is my opinion.
