Can OCD be considered a form of hallucination since it can mess with your perception of reality?

i kinda experience that too, i have a fear of weed and i’ve tricked myself into thinking i was high many times so it resulted in me seeing or feeling certain things that weren’t actually happening

I had to go to the ER for a bad panic attack and they thought I either had schizophrenia or I was on meth and I’m like no it’s just really bad OCD thoughts. So I would say yes definitely a form of delusions.
