My gf has a super visceral reaction to backmasking, especially “running away into you” by John Frusciante.

Is that a genuine reaction or is there some performative aspect to it? I’ve seen and heard some EXTREMELY distressing visual/audio and (while disturbed) can cop it pretty easily, whereas she will have a full on neuro-divergent freak out. Is this genuine? A reaction to some sort of psychological mechanism?
