I just found a word for this "confabulation." " Persons living with dementia often get details mixed up and sometimes fabricate stories from fragmented memories. The person living with dementia believes without question, that this memory is complete and intact. Since the belief is absolute and sincere, it makes no difference that they are illogical, impractical, or even impossible" This is an insert from an item I was reading.

I do not think it is fantasy, but an earlier reality - the first parts of their lives, that
we often do not know about. So it does come across as fantasy to us.

Jay is in a different reality most of the time. I've learned to live with it. You should just agree with your loved one regardimg their perceptions its easier.

go to the Alzheimers web site and they have a wealth of information on there. Read the book "The 36 hour
Day", it is very enlightening.

If its unbelievable to you, ex: "my loved one will talk about the children being there before church, but now they are gone" (and a thousand more moments like that) we have leRned that she does believe it and dont dwell on it or argue with her. Bottom line what's the point?
Heartbreaking buts its her reality for the moment
