I hear things

[Supafly345]

It may be your mind translating similar sounding sounds into whatever word or voice it can match it closest to. This happens all the time with sight, I don't see why it can't happen with sound too. I don't know why you are becoming more aware of this if that is the case though- it could be that you are listening for them more since the first time it happened or something.

This isn't a sign of any disorder I don't think, I your brain is just working overtime to make sense of nonsense.
