When my grandfather developed dementia, he claims to have seen a little blond boy who kept stealing his shoes. Problem was, there was no blond boy. My mother has been diagnosed with dementia after a very bad fall (spiral fracture of femur, then she stood on it and broke it; 8 pins, 1 plate later.....) and now SHE'S seeing a brown haired child she claims she's being told to watch (babysit). She's in a rehab/nursing home. No children. Is this common? I am so new to this and I don't know what to think.
