Blindfold chess

 what is the average rating for someone who can play blindfold chess?   Now I am rated 1400 and I always play in school two blindfold chess games at once vs. another 1400 and a 800 and I beat them even when they play on board.  I can somehow recall chess games that I watched/played only once. is that connected to the number of games I played or just because I have amazing memory?

Is that normal for amazing memory?

Playing blindfold is hard, playing blindfold at more than 1 board is even harder.
Usually the blindfolded player is >200 stronger than his opponent. Beating a player at equal rating blindfolded is rare.
Recalling games is a sign of good memory. Most strong players can recall games of themselves and of others.

And I am not even that good...
