500 micrograms LSD. Experienced "personality regression." I lost my ability to process and generate language. I had only emotional responses to noises that I heard. Some of those noises were human voices, but they sounded like the teacher in Charlie Brown cartoons: just a wah-wah-wah-wah trumpet-like sound that was more a placeholder for the speech than anything like real speech. The emotions that the sounds caused were basic and strong: a longing to be closer to a voice whose timbre I recognized, pure joy at hearing the rhythm of a song that I knew. Once my language facilities came back, I could remember only the "shape" of the experience, but none of its contents. I remember feeling the emotions, but I don't have the usual internal voice that narrates them. I knew there were sounds, but I can't describe them well, except in terms of my emotional response to them.
