In my experience not everyone with schizophrenia / a schizoaffective disorder is able to communicate their experience very well, but some of them have published content about it and it can be quite a fascinating research subject.
I'm not aware of any articles myself, only videos, but if you're open to that I have a few recommendations that you could start with.
It may also be worth checking this one out, which is a review of various "schizophrenia simulations" (in other words, depictions): https://www.youtube.com/watch?v=60n7ZP3Cj-4
I don't have schizophrenia myself, but I have DID and a few other mental illnesses, so the topic of mental illness in general is particularly interesting to me. Learning about others' experiences can teach me things about myself, too.
