I believe the song Lateralus is about being at the crossroads of a cluster b
personality disorder. There are two choices, get treatment and keep going or spiral out (of control) and end the suffering. Spiral, keep going., spiral out, keeping. It an inner battle, a constant tug of war. Black then white is all I see; that called splitting, red then yellow is anger and happiness; which can come and go all inside an hour or a minute.
Over thinking, over analyzing, separates the body from the mind; that's about
dissociation, a maladaptive coping mechanism to cope with trauma.
