hi SMG.. i did a quick search here at PC for you.. noises and images, from what i have read... are common in the 'schizophrenic' experiences..... not really educated in that area and sometimes the language is pretty scientific...

i occcasionally hear a noise which doesnt seem to have a source... its a little mystifying, but comical also when i discover it was the neighbors music, or a radio turned down low.... when tired i will sometimes hear 'tunes' from someplace... my ears may ring... thats in an exhausted state of mind tho... not a usual thing for me...

hope this helps some...
