I'll cut to the chase. I want to be able to summon a girl (who does not actually exist) and make her my girlfriend. I want her to have a very specific personality type and to do certain types of things, but I also want her to act on her own. In other words, do and say stuff, based on the personality traits I gave her but without me consciously willing her to do/say them.

Is this possible? Does anyone do anything like this? If possible, how hard would it be to do?
