Audible Hallucinations?

I keep hearing the tune of ring around the rosie repeat all evening long. I don’t have neighbours at the moment. It’s everywhere in the apartment I go. I have never had strong audible hallucinations as a BPD symptom but I’m starting to seriously believe I’m hearing things. Anyone ever deal with audible hallucinations before? I’ve had the lots of visual ones, mostly of shadows that weren’t really there, and the odd other thing. Never heard anything though. It’s starting to freak me out.
