Yes, often.
We as thinking beings consider ourselves to be constant. The trail of memories leading from our childhoods to today make it feel as though we are still that person who lived through all of those times, but we aren’t. We can’t be.
I have memories belonging to an 8 year old boy in my mind, he had the same name I did and lived with parents who also had the same name as mine, but I am a much older person - older than his parents, even - and I share almost no common ground with this boy. How can we be the same person, when we are so obviously different?
I am physically a different person to this person of my memories, and I can’t be sure he exists or existed. He may simply be a figment of my imagination, a story I tell myself of where I have come from but made up from whole cloth.
