You're seeing dead people!
(only funny if you have seen the movie, right)?
Have you tried turning off the transparent shadows and such to see if it affects the visual? Maybe your char. has an innate abiltity, like that girl in the Spellhold, who saw things no one else did, and it drove her crazy...
(I am not much help on this one...just havin' some fun...sorry)
