When you envision yourself as the main character of the movie version of your life, highlighting the parts of yourself that would make you unique or likable. This syndrome focuses on the self more than any other person, much how movies or television have a story primarily based on one character.
Cindy has main character syndrome and am constantly imagining herself as the title role in the movie version of her life: THE UNTOLD CINDY STORY.

That’s what your entire interpretation of the Bible is tainted by.
Hym “Main Character Syndrome. The idea that you are the protagonist of the story or that you should be the main character. Is that how you’re acting? And that’s what I mean about ‘Only telling half the story.’ Because you’re not just the person who nobly endures the suffering at the hands of the mob. You’re not just the person who’s called forth to adventure. You’re the mob that demands God’s angels be given to them. You’re the horde that rends Jesus asunder. The tyrant the needs to be taught a lesson by having his kid slaughtered. I mean... are your REALLY the Abraham? Are you REALLY emulating Christ? Or are you just acting?”

A somewhat naive term referring to "When someone thinks they are the main character of their life."

It is naive because everyone IS the main character of their life, everyone is the main character of their own story. Believing you are the main character of the whole world, or all of time is called narcissism, and this term is basically a way to conflate things like focusing on yourself or your ambitions with narcissism.

I would not recommend using it unironically, or towards this definition at all if you have any self respect.
