My FIL had hallucinations that would really disturb him as well. I got the idea to try to convince him that either I or my husband had "taken care of it" and sometimes had to explain how, but it worked because he had trust in us.
One time he just knew that there was a wall of water on the other side of the closet that was going to come crashing down on him in the middle of the night. There is no water or even pipes near that room or the adjoining room. I finally convinced him that my husband (his son) had been working in there all day long and had finally not only drained all that water out but had everything fixed so that it wouldn't happen again.
These are not hallucinations to them, they are real (as you know) so if we treat them as real, sometimes it can help. It would be worth a try anyway.
We also had issues similar to what you have experienced, and had to ask that person (his other DIL) to never bring up the subject again. It didn't fix the issue (he continued to have issues with this person), but it did keep my FIL from having more hallucinations because of a visit.
