"Slip like Freudian, your first and last step to playin' yourself like an accordion."
Sigmund Freud believed that dreams and 'Freudian slips' (accidently letting something slip which isn't related to what's going on) reveal something about your innermost desires and repressed thoughts. MF DOOM's telling us to analyse these things; to learn something important about ourselves from them. So you'll be 'playin' yourself like an accordion', which involves a sort of smooth flow in its playing technique. I get the impression the whole song might've been written around this line.
