Where oh Where?

For the last several years of her life, Mom lived with advancing dementia. Strokes - large and small - hastened the process but mostly Mom was there in some form or another.
But one day, while sitting with her, I had the experience of her looking for herself. That is the photo below that I titled - Where have I gone?
Spending time with Mom educated me, puzzled me, softened me and opened me to questions that I have no answers for.
