This has been happening for many years, but it now becoming an issue. I'm wondering if it is mental or physical - I can't seem to find anything else suggesting it is an actual illness at this point except stroke, and I know I am not having strokes.

Basically I get these "attacks" where I can be listening to the TV, or music, or conversating with someone etc, or on the phone - basically listening to LANGUAGE(musically, everything stays the same/ambiently there are no changes) - and suddenly for about 10-30 seconds, I can't UNDERSTAND any of it. Now, I can still HEAR it - but the way I hear it changes - it literally sounds jumbled, as if I was hearing another language or they were speaking nonsense.

What the heck is this, any idea?
