I've just read the earlier posts and I am going through exactly the same with my mum and her hallucinations. She is seeing so many people in the house. Doesn't seem to recognise it as her house, thinks she's in a hotel so the other guests might steal her things. I can't begin to tell you what I pull out of her handbag on a daily basis which she is hiding from "the people". There have been birds on the carpet, dogs, cats and bugs. There's plenty more but I won't go on. It's weird that so many suffer the same hallucinations. Honestly, I do lose my patience and I defy anybody who cares for someone with dementia to stay calm all the time. Especially when I spend hours searching for things!
