cant tell where are sounds coming from and repeating sentences/words in my head

For a while now I havent been able to tell anymore where sounds come from. For example If someone calls to me I might search my phone for a long time cos simply I dont know where the noise comes from, even when my phone is like next to me.

Also when I have "heard" my thoughts for a while/talked to myself in my head, today I noticed that I was repeating this sentence in my head over and over again. I actually sang the sentence ("eleven, twelve, one two three four") for like tens of times..

Does someone else experience this? ...And like always, Im afraid of going schizo..
