The song is about depression and contemplating suicide. The lyrics, "Now the red ones make me fly, and the blue ones help me fall" may refer to antidepressants or other drugs ("Reds & Blues" in particular is drug slang for the color of commonly abused amphetamine & barbiturate pills respectively, uppers & downers). According to lead vocalist Gerard Way, "This song is about suicide - don't do it."
The plural form of halo is either halos or haloes.
