It shouldn't be too hard to shoot a surreal movie without special effects. You know what surrealism is, it's pretty much the reality of your dreams. The world seems perfectly normal, just off a bit. For your movie, you could have two people talking to each other, except they're carrying out seperate conversations. For example:
Guy1: So then the light turns green and I step on the gas...
Guy2: I know, she said the bananas were ripe and I believed her.
Guy1: Exactly, that's when the truck hit me out of no where.
Guy2: Yeah, I'm never talking to her again.
Ya know, something weird like that. Just try to keep the atmosphere dreamy. Shoot handheld to make it feel like it's floating. Add some weird noises that none of the actors respond to. Heck, put a guy in a monster suit and have all the actors happy to see a monster show up. It's not too hard, and if you go crazy with it, it might be one of the more fun assignments you'll have.
