Heh, I created a sorta alter-ego as well when I was small.
I have a huge imagination, I had it when I was small as well so I went like.. *imagined a full galaxy, with people and stuff* and one of the races in it were "The Ancient Entities", beings that existed before existence itself, and particularly, their most powerful ''warrior'': [Alpha]-0mega-.

When I entered him as my alter-ego in my dreams (went easily, dunno how lol), I became him in my dreams.

Name: [Alpha]-0mega- (Or Alpha Unit Leader, 0mega)
Appearance: Me, but cooler with black clothing most of the times. And he always has a Samurai like Blade known as the "Alpha Blade" with him. (Same age as me too)
Abilities: Anything that's possible or Impossible.

Where you need a special technique to fly, I need nothing.
My "alter-ego" is near perfect , I can do anything without having to say it or to move.. I could technically play a whole dream without saying anything or moving.

But enough showing off my alter-ego. (I actually have an alternate theory now, that instead of ''posessing the alter-ego'', i'm supposed to do something different, but i'll post when that works out.

I can say though that he's really right, the alter-ego method works REALLY good (at least for me it does )

Also i could anyone tell me how to make my Alter ego better as in more relistic and so i can easily tell there not me.
What I did was, basically focus on my ''alter-ego'' and force him into my dreams (Through the power of focussing), and it worked.

So just figure out how you want him to be, and Keep focussing for like... 10 minutes that you want him in your dream as your alter-ego. (It worked for me, just less than 10 minutes lol)
