New Blood (2002, Soi Cheang)

Dude survives the suicide pact with his now-dead girlfriend thanks to three blood donors: architect Eric, cop Lok, and cute girl with mental illness Joy. Now they’re all seeing blood visions and being haunted by the bald-capped dead girl. This drives them all nuts – Eric throws blood around at the girl’s funeral, a possessed Lok kills his dad, both men (and the surviving lover) die and Joy ends up in an asylum. Grim movie, to the point of stealing the Requiem for a Dream music during the blood transfusion scene.
