Hallucinations are common with many people even those without any sort of psychiatric disorder. As long as it's not interfering with your life and your day to day functioning I wouldn't worry about it. I get tactile hallucinations from time to time; when it happens I always get a fright haha. Also occasionally visual ones in my peripherals or I see bugs crawling on me (this has only ever happened in therapy for some reason! And if I'm being honest I'm not sure if it is real or not gah). But I've never been too bothered by them.
