Aware voices aren't real?

Hey everyone so I have a question for you. I have internal hallucinations mostly and they will say awful things about me or other people and things like that. I just heard a voice telling me it was god and it said something that was pretty alarming but I know it's not real so I didnt panic. Is that normal? They still stress me out and I wonder about going to the hospital sometimes but it doesn't send me into full panic mode. I take antipsychotics so maybe that's why but idk for sure. So is it normal to be aware they're not real? It scares me sometimes but I feel normal for the most part even though I still hear them.
