There isn't really anything special with the Time Lord's mind. He's just, basically, a genius. Rigorous and passionate studies will put you on the path to having a greater intellectual capacity.
As for the "Supergirl" spell...like above, that's fantasy, that's not real magic, HOWEVER, there is an alternative. One can learn how to manipulate and live out their dreams in a more direct manner. Being able to impress your desires for reality in your dream world, can let you access those desires and live them out there...
But outside of that, sorry.
