Your experience with visual hallucinations saddens me. Mine are more audio then visual. If I had to deal with what you do, I think daily living would be much harder. I sympathize with you.
I wonder if what we experience would be able to be more categorized and better able to predict if Doctors would begin separating audio / visual (other senses, like the people who have trouble with shower stimulation - physical?).
Sorry, got sidetracked. Really I had read and not responded to this post 2 days ago, but thought of it so much I had to go find it just to say - hugs, you are not alone, sorry to hear about the bad hallucinations.
Best of luck to us all.
