in general its having symptoms that seem like psychosis/ or psychotic symptoms (hallucinations, delusions, not really in tune with whats real....) but the symptoms are not really psychosis/psychotic.... they just seem/appear to be..psychotic symptoms....

a common example that happens to me is seeing something that isnt real a shadow , or blip in front of me. this can fall into seeming like a psychotic episode but in reality its a flashback, it just appears to be a psychotic symptom.
