One positive is that you know you had paranoia and hallucinations. If you didn't, you wouldn't be telling him that. You'd still be having them and/or believing them to be true. Knowing you had them (past tense) may lead him to believe you're improving.

If you continue to experience more disturbing events, let your psychiatrist know. If he doesn't adjust your medications with continuing symptoms, then maybe you do need to see someone else, especially if it is distressing you, or as bluebicycle wrote, making you feel a danger to yourself or others.
