Am I Being Paranoid

So about an hour ago, I get a call from a woman, a phone number that I don’t recognise, she says “is this (name)?” I said “no, this is (my name)”, she then says “oh sorry I must have the wrong number” and I’m like okay no problem and then she hangs up. 

It was a landline number from Dublin (I live in a completely different part of the country) and so out of curiosity I searched the number in Google, it is the public phone number for A GARDA STATION. I know people call/are called by garda stations for loads of different reasons, but am I being paranoid/irrational to think that admin mistakes like that don’t really happen often and so someone (maybe involved in crime or a witness or something) has given my phone number ?! 

I’m probably going to get ridiculed and trolled for asking this but can someone please tell me am I just being paranoid or should I ring back the station and ask them whether they were given my number or if it was just a number typo mistake ?

I find it quite unusual that she just hung up without giving any context or anything, I would have thought that if you get a phone call from a Garda station they would at least introduce themselves, not just say “is this (name) ?”.
