I have tried looking on the internet and the FAQs but i couldn't find an answer to this.  
It seems like when you cast a spell on yourself and spell turning is on it gets reflected to yourself...but you have spell turning on (unless the charges were consumed by your spell) so it should create a resonance field.

This doesn't seem right, but there's no exception on spells cast to yourself in the spell description. The only thing one could say is that the resonance field paragraph says "attacking spellcaster" which implies an hostile action, but I don't really want to imply things and this seems just a case of bad wording
