Hi Moose,

I have experienced what you described. To one degree I'd say that severe racing thoughts caused a similar experience. In more intense cases, psychosis.

I recall a period, years ago, when my mental state was quite dysfunctional. A few specific examples actually were in concert halls. My husband forced me to join him at concerts at times when I really shouldn't have gone. I believe I might have written about one case years ago. I'll try to find that, but may not have luck. My memory is a bit blurry about such times in psychosis. My limited recollection of at least one of those times matches what you describe as cachophony.
