What did dr. freud say to the guy say to the guy who thought he was mickey mouse on day and donaldduck the next?

Dr Freud said;

"It appears to be very obvious to me that you are experiencing Disney spells but at least you're not Goofy! "

This is both a figure of speech, and a little play with character names. Disney Studios are the proprietors of both the Mickey Mouse and Donald Duck characters, and Disney may sound somewhat like Dizzy; rather than saying "dizzy spells", the specialist proposes it's "Disney spells"; Goofy is yet a third Disney character.
