Living in worlds with dragons, unicorns, dwarves, giants, wizards, super heroes and evil villains. ...... requires a player to sink into his/her character and take on that character's persona. It's a skill that requires creativity, imagination and a willing suspension of disbelief.
And when all of the above happens you can identify with your character and your character becomes I rather than my character. That is the immersive power of role playing games.
