12. Eternal Sunshine of the Spotless Mind (2004)

Another Charlie Kaufman movie, this time directed by Michael Gondry, Eternal Sunshine of the Spotless Mind will have you re-evaluating your relationships when the credits roll. Jim Carrey and Kate Winslet are two former lovers who have their memories erased. The film uses lots of flashbacks and vivid imagery that explores the nature of love and relationships. Both Carrey and Winslet are sensational and bring vulnerability to both their characters, while the ensemble cast featuring Paul Rudd, Kirstin Dunst, Elijah Wood, and Mark Ruffalo is fantastic.

13. Waking Life (2001)

Richard Linklater’s Waking Life is one trippy movie. It’s an animated feature addressing all the big questions, such as what is free will and what is the meaning of life? The movie follows a man wandering through a dream where he meets various characters and tries to understand the world around him.

This is another film that will have you thinking about what you saw long after it’s ended. It raises lots of psychological questions and issues about life and death. The animation also adds to the concepts in the film and helps bring them to life in a dazzling way. 

14. El Topo (1970)

Written, scored, directed, and starring Alejandro Jodorowsky, El Topo is one bizarre film. Described as an avant-garde Western, the plot doesn’t make a heap of sense and involves everything from shootouts and little people to religious iconography and nudity. 

It caused quite a split amongst critics, with some loving it visually, thanks to its trippy, drug-fuelled cinematography, while others had no time for the confusing plot or the controversial rape scene. Whatever the critic’s thoughts, it is a must watch for movie fans after a truly trippy experience.

15. Naked Lunch (1991)

Based on William S. Burrough’s novel of the same name, this cult flick is one hell of a visual trip. This adaptation of Naked Lunch comes from the mind of David Cronenberg, so you know it is going to be ultra strange. While the plot revolves around an exterminator who gets high on the insecticide he uses and begins to believe he is a secret agent who must kill his wife, it’s the visual aspect that really makes you shake your head in awe.
