...Maybe. It sounds like a similar concept. But the Egyptian concept of the soul involves five parts instead of two. [That's not even including the three other parts of the soul that were subsets of the first five.]

But the Akh, if it's reanimated, can affect people too. Like the "lower soul". It sounds like your "higher" and "lower" souls are just a simplification [or misrepresentation] of the Ba, Ka, and Sahu or Akh.
