The White Sound (2001)

Driving through the countryside, Kati (Anabelle Lachatte), Jochen (Patrick Joswig) and Lukas (Daniel Brühl) take some magic mushrooms. One of them, Lukas, is not coming down from them. Hearing voices like multiple different low turned radio programs, changing and mixing altogether. The diagnosis of the physician: paranoid schizophrenia. Not able to filter and interpret the sensations presented he encounters fear, inner voices, paranoia and is drifting away from reality.
