Just recently and I mean over the last week Mum is seeing people who are not there and what is more she knows they arent there so I am not too sure what she means. I think she means that she sees a shadow of a person but knows that when she turns they wont be there. We have talked about it and she isnt frightened about it. Has anyone experienced this? My mum has mixed dementia...Vascular and alzheimer's and they think probably Lewy body dementia as well stemming from early signs of Parkinsons
