Guys, question, can ocd make you like, smell something that is actually not true, for example with Contamination OCD? like simulate Odors that are actually not there?

Can ROCD make your thoughts and feelings feel 100% true or real???? Like I can have a thought or feeling and in that moment it feels real or should it not feel real until the ocd latches onto it?

With ocd can the thoughts themselves feel entirely true???? Or is it just the narrative around the thought that feels true/real?

I was diagnosed with OCD around the age of 6, subtype- contamination primarily. It calmed down as I got older and I assumed it had gone away, but also didn’t realize it can show up in other ways, and it still had been effecting me which I know now. I’m not 31 and I’ve been in therapy for a year and it’s helped a lot, although I sometimes get thoughts that what if some of the stuff I’m dealing with isn’t ocd and I’m exaggerating. I feel like thoughts will feel sticky and I’ll do certain compulsions but then the thought eventually vanishes if I do it a few times which makes me think maybe it’s not OCD since other people/friends I know would probably do the exact same thing. Not sure if I’m making sense, but I guess my question is if that thought comes up with anyone else? Just being unsure if something you’re doing actually is ocd or not.
