Greetings,
A medical professional could best answer your question, though, from my understanding, stressing over anykind of hallucination/delusion, only promotes more of them to come, and/or become more severe.
I was told by my psychologist to pretend my hallucinations/delusions were as if I am dreaming awake, and to therefore, dismiss them. After all, mentally ill, or not, has crazy dreams, at least, every once and awhile, though, they are simply the mind being creative with the leftover, possibly unresolved thoughts bouncing around in our head.
Nonetheless, as I mentioned before, medical professional, could help you get to the underlying cause of your hallucinations and, I have no doubt, help you efficiently rid of them.
Best of luck to you!
Have a good one.
