Ok so anecdotal example: when I was a teenager I was sick with something and took nyquil. After I took it I lied down in bed and I saw bugs crawling all up the walls of my room despite knowing they weren’t there, and forced myself to shut my eyes and go to sleep. Sometimes people can distinguish between “ok im clearly hallucinating” and sometimes they can’t and wind up doing crazy shit (i.e. some people take angel dust and jump off a building thinking they have wings and can fly)
