I have been clinically diagnosed with schizoid personality disorder (SPD) since becoming an adult. A common misconception others have about this personality disorder is that it is psychotic or just a synonym for schizophrenia. It is neither. People with SPD from my knowledge and personal experience (I am not a medical professional) do not usually experience symptoms of psychosis. The DSM-5 considers SPD as a "pervasive pattern of detachment from social relationships and a restricted range of expression of emotions in interpersonal settings".
While I do regularly experience vivid and horrifying nightmares — name pun intended — I have no memory of any hallucinations, save for minor auditory ones heard during a single episode of acute sleep deprivation during one really hot summer. If you're curious... I simply thought I heard my name being called among background noise. This occurred many years ago and I have never experienced any hallucinations again — and I question if that moment was actually a brief lapse in consciousness rather than an actual waking hallucination.
Anyway, suffice it to say... Equating the term "schizoid" with "schizophrenia" is inappropriate, albeit forgivable. Had I never been diagnosed or heard of SPD in the first place, I would probably hold that same misconception.
