No, no, spit your shit! I genuinely love the idea of schizophrenic Protag. I think the 'monsters' (I think it's phrased that way?I haven't played this game in a while) are in reference to his parents/mom rather than hallucinations or delusions, but honestly? Since I haven't seen anything confirmed yet, I'm clinging to that schizophrenia (or Psychosis) headcanon.
