in pic it's an uterus (uterus pussy, dunno. the light on the top looks like a clit). when the girl gets out of the screen, it's reality happening, it's a 3DPG girl. when she vomits in his mouth it's not literally a drug, she makes him get high on love. but love gives you good and bad trips. his good trip turns into a bad one, because she's treating him like shit/rejecting him. look at how her cute version is being held up and her bitch version attacks him. he wants to reach her old self (when she loved him) but her new self, the final boss, doesn't let him (which represents her rejecting him).
