The diagnosis of "pseudohallucinations" is made if they don't have the characteristics typical of hallucinations in schizophrenia - that is, there are third person observable differences. Without these differences it would be impossible to tell and, since psychiatry at least aspires to be an empirical science, the possibility is generally ignored. However, you can have delusions about anything, so it should be at least theoretically possible to have a delusion that you are having a perception. Patients frequently report delusional memories of perceptions: that is, they insist that they had a conversation or experience that they could not even have hallucinated, because they were under observation at the time of the alleged incident. Suppose this process is happening "live", so that they believe they are hearing a voice and responding as if they are hearing a voice even though they are not even hallucinating such a thing. We might speculate that the actual experience would surely feel different to the mere belief that they are having the experience, but if they could notice such a difference they would not be deluded.
