I didn't finish it but started watching a Japanese film called Symbol.
I like the 'head fuck'-type film where you don't know what's going on or what will happen next. This was too weird for me though.
It cuts between a Mexican man trying to become a wrestler and a Japanese man waking up in an empty room and he's wearing kids' pyjamas.
There's a strange object sticking out from the wall which he touches. From that emerges what looks like a statue of a cherub. The thing he touched turned out to be the penis and balls of the cherub.
Lots more cherubs appear and then retract into the wall, all with their genitalia now left. As he touches each one different objects appear in the room. It could be a barbecue, a table lamp, anything.
At one point he touches one and a countdown begins. He's scared and apologises, fearing for his safety. At the zero a giant buttock appears from the sky and farts gas into his face.
At this point I gave up on the film! I felt like I was on a bad acid trip!
If you want to watch it, and I haven't spoilt it for you, here it is. Let me know if it was worth it.
Or the 1 minute trailer
