Does anyone else ever have their inner voice/monologue suddenly change? This has been happening to me for as long as I can remember. It will still be my own thoughts, but the voice will be different. It usually becomes this big, loud, booming, terrifying voice. Even though they are my own thoughts, the voice is terrifying and unbearable.
When I did get voices, often there would be a screamed command. Yes it was booming too. sorry you are experiencing this.
