Just screaming??? or are there words and ideas that she is communicating with the screaming??
what is the exact nature of the process? how does it begin??
what are the precursors or the preceding events that seem to be occur prior to a screaming event???
God is in the details, and while I get the overall nature of the screaming that you are feeling is a problem for you, I am not getting the exact nature of the event.
So before I offer advice on what to do, I gotta know in
as much detail as possible "what" specifically and exactly is going on.
Finally, everyone is different, which means that your daughter is and does interpret her own world uniquely...functionally that translates into what you mean when you say and do things, may mean something slightly or maybe even a lot different to her. It's sorta like the stuff that exists between certain cultures where interpersonal space means one thing to someone from one country but something entirely different to another country.
and, it could be the littlest thing that you aren't even
aware of that is somehow getting "turned on" by your daughter, and it completely baffles you and maybe even her.
I can't tell how subtle stuff gets to trigger big stuff.
I have clients who blithely tell me about their days and are totally unaware that their beliefs are driving their discomforts and fears etc, and they are totally oblivious to the underlying goofiness...and I say goofiness because it is not mental illness or craziness...it's just accidental programming that somehow got plugged in and now is operating without conscious awareness and is making them "nuts" or making their life really inefficient.....and it's stuff that every one has....in the oddest places and oddest ways...
