Yes, I agree with Scott. My husband had hallucinations and delusions and arguing only produced agitation, so best to just agree or try to eliminate the source of the hallucination. My husband insisted the neighbor was flashing lights at him. I discovered it was the wind blowing the bird feeder and the street light was shining off that. No amount of trying to explain to him so I just removed the birdfeeder and that eliminated the problem. Sometimes just agreeing and going on is best.
