The Alice in Wonderland/drug narrative connection is elementary and overused. Dig deeper. Also, the setup is too familiar. Also, look up Schizophrenia. What you mean is he has a multiple personality, or suffers from Dissociative Personality Disorder. With only a handful of exceptions, Schizophrenics are people with delusions that are more likely to harm themselves than anybody else. I advise you to expose yourself to good surrealism. It doesn't need excuses like Schizophrenia and drugs. Lynch never says "he was on lots of drugs" or "he was mentally ill", neither does Jodorowsky. Expand your horizons artisically and expand your limits. Take a look at the films in our top 100 lists.
And for your benefit, the last words on weirdness and perception:
