I reccomend "You, the Living", "Fireworks", "The Phantom of Liberty", "Delicatessen", "Blue Velvet", "Wild Side", "Performance" and "The Spirit of the Beehive"
If you like Amelie you might like Kamikaze Girls, I'm A Cyborg and C.R.A.Z.Y. - they have similar narrative structures and surrealist moments. Other general surreal(ish) suggestions include Cube, Central Bazaar, Inaugaration of the Pleasure Dome, Brick, Mulholland Drive, Fantasia, Yellow Submarine, Wild Tigers I Have Known, Scanners, Braindead, Oddsac!
