i'm not sure, but i've been told the different color enegrys or auras mean different thing, i but sorry i wasn't told what the colors mean i would like to know myself, but i it could be the purple energy giving you the shocking feels, cause as i said mine is purple and i seem to have an electric field around me (i shock alot of people and fuzzy sounding radios go normal around me too)
Jupiter rules purple. Purple rules the crown chakra.
Some say and the nervous system. This is the most sensitive and wisest of colors.
This is the intuitive color in the aura, and reveals psychic power of atonement with self... Also Intuitive, visionary, futuristic, idealistic, artistic, magical...
