In terms of depth work, I did a lot of work with my first therapist around understanding the meaning of my delusions. Working with them as metaphors rather than responding to them as frightening or as random manifestations helped me to understand and incorporate reality.

Are you familiar with the Helicopter View? It's not specifically for psychotic experiences, but the idea is that you attempt to hover above the experience to gain a more objective and complete view. I would use a simplified version and ask myself these questions:

What does this delusion/hallucination mean to me? What does it say about me?

How would my trusted friend respond to this delusion/hallucination? What would they say was happening?

What would an outsider advise me to do? What might a trusted professional say?

It's long and complex work, I don't think there are easy tips really. For me, distraction only worked til the distraction ended, the delusion ultimately outlived the activity. Keep safe.
