Dad with diagnosed early stage dementia called and left a message that a son I did not know was with him. He wanted me to come over and meet him. Then called my husband and told him the same, husband asked to talk with him and Dad said he was born with an affliction and could not talk but smiles a lot. This is doubly upsetting as before I had my 2 children I had miscarriages. Could this be hallucinations or an attempt to bring us over to his house? We were there twice yesterday bringing groceries and such.
