Not at the first times, I was just very curious, but then I tried to deliberately focus my attention to my stutter, and I asked the question why it happens. I thought there is some unconscious problem that I may realize when in psychedelic state, but nothing ever came. Obviously, we are conscious about high level processing that our brain does, and the major low lever processing will always be unconscious (or maybe it would require huge doses of psychedelics ?). Now lately when my stutter worsened after I had covid (I started to stutter even when I talk to myself which I never did before) I realized it really has nothing to do with something hidden and unconscious. I guess experience of other PWS would be similar, so that stuttering in its root is just a technical (purely neurological) problem even though it feels like it is not.
