Diana, when it happened to my neighbor, she also saw bugs, so her daughter and I actually had to pretend to catch them........On hallucinations, don`t try to convince your dad that he`s seeing things. As a psych nurse, I have learned to just go along with it and reassure him your looking out for things. Telling him things aren`t there might make matters worse.........Let me know how things work out.....Prayers, dee
