Hallucinations aren’t the defining feature of schizophrenia/schizoaffective (while they’re extremely common) but rather disorganized thought. If you have thoughts that bridge together/conclude even though there’s no logical way they’re even remotely connected, you probably have schizophrenia, if not, you may just have something like bipolar type 1 or another disorder that can give you psychotic symptoms. I have bipolar type 1 with psychotic features but I was convinced I had schizophrenia before
