Has anyone else run into this problem? My Dad has hallucinations, and this seems to be the one that occurs the most. He holds his hands palm-side up and asks what he should do with the catgut or strings on his fingers. He continually rubs his hands together to rub the catgut into a trash can. Usually I'll just tell him to rub it off and let it fall onto the floor, where later it will be vacuumed. He seems fixated on this during the day. Sometimes he picks on his fingers, trying to get rid of it, until his fingers are red!
