you know, i cant help but recognize another hp reference here.
the stag, was harrys patronus - a white stag. it served to protect him from the dementors (who basically suck out your soul). it also could serve as a messenger on a sort of spiritual type level.

the other characters had individual patronuses as well, each varying animals.

there was also a silver doe (basically white that was emanating a moonlit glow, hence silver) that acted as a spiritual guide on the behest of someone looking out for him.

so i bring this up because i do feel this ties in with whats happening in our world today. so many things in that series do. the semblance of these beautiful white animals bring us a sense of peace and tranquility and wonder - which helps elimate fear. much like the patronus.
