I think there's something wrong with my ears..

Over the past few days.. Over my countless conversations or even when they are like not talking to me.. but they're just blabbering and blabbering.. but all i can here is just crap coming out of their mouths...
It feels so strange.. cos they can either appear happy or frustrated or just talking, but i am like totally cant hear them at all and just here noise coming out of them.. I hope this doesnt continue, as it will cause quite abit of misunderstanding sia.. but one thing i realised that this usually happens over the weekend.. haha so weird.. i wonder if anyone else have the same problem.. maybe i should see a doctor ..
