I never understood how that worked... As soon as I heard the "Nightmare Moon is separate entity" theory I believed it, but always thought of her as Luna's evil side, jealousy and bitterness manifested into a form of its own to possess her like Yami Marik, because it said in the intro "The bitterness in the young one's heart had transformed her into a wicked mare of darkness". Like the demon Sunset Shimmer, Nightmare Moon came from within Luna, just with help from an "outside force". Yet the way the comics tell it, Nightmare Moon was a dark force from the moon that took advantage of her bitterness and possessed her, that's not "the bitterness in her heart transforming her", it's leading to a demonic possession by the outside force itself.

The way I always saw it, the outside force (King Sombra maybe?) sensed the resentment in her, so he magnified it so it became stronger and stronger and began to influence her... and when she took the final step to move against Celestia, that allowed her darkness to manifest into Nightmare Moon. And when the Mane 6 used the Elements, Nightmare shattered to pieces, leaving only Luna with the jealousy lifted.
