Obl. nitpick: you mean paranoia, presumably. Schizophrenia is a dissociative/psychotic disorder, paranoia is the irrational belief that you’re being persecuted/watched/etc.

Btw, in this case it can’t be paranoia since the belief was not irrational - the author was being watched.

You are right, I meant paranoid.

>Btw, in this case it can’t be paranoia since the belief was not irrational - the author was being watched.

Yes, but I mean being overly cautious in the threat model. For example, birds may be watching through my window, it's true and I might catch a bird watching my house, but it's paranoid in the sense that it's too tight of a threat model.
