hmm, I don't know about your meds, but maybe it could be med-related? Was there a change in meds before this started? Or any other significant change in life?

I googled 'lamictal side effects hallucinations', same for Saphris and apparently hallucinations can be a side effect? Maybe you can google/look for the other symptoms too?

You could ask about your concerns to (another) doctor? Or possibly have a change of meds?
