I fear this post is asking the impossible. I want to know how it feels for my grandfather, see the world through his eyes. He now lives in a home and he has advanced Alzheimer's. He sleeps a lot, stares blankly ahead, but has flashes of recognition. He can't really speak anymore and he looks puzzled. He doesn't recognise his family in any rational sense, but I sense he feels the bond between us and is comforted by us.
