The Composition of Self Being

If I fell asleep and woke up duplicated into two bodies with identical memory, which one is me? An open question on what self being is made of.

What is the composition of self being? What does my self being consists of?

As of yesterday, all I thought of was that the memory of my brain: my experience and my emotion was the only thing I need to be myself. As long as my memory can transfer, I could be in any kinds of physical form and call myself that I am myself.

But, a thought came across my mind.

What if I fell into sleep, wake up and find myself duplicated into two different physical form with the identical memory? Who am I now? Which of the two different form is the "I" that fell into sleep as of before falling into sleep?

And if I could define that one is myself, then who and what is the other one?

Is this the kind of situational question that could never happen in reality, such as "can I be almighty" or "can I go back in time"? (I believe that in the future, I may be able to go into the past but I cannot go back in time.)

Then, is it ever possible to define the composition of self being?
