Aura help!

Hey guys I'm new to this forum and super stoked to be a part of it. I am trying to get some insight on an issue regarding my aura. For the past few months I've been practicing seeing/reading auras and I've had much success and a few friends of mine have also started. One friend of mine repeatedly sees my aura and describes it but she also notes of a bright orange spherical essence above my left shoulder, although it appears to be drifting upward in a halo-ish kind of way. I was wondering if any of you guys know what that means or is. If tried google but I haven't found any reasonable answers. Sometimes the orange is of the otherside of my body, it doesn't appear stuck on the left side of my neck. Thanks guys!

Could this be a guardian angel? Some people say they sit on one side of you to protect you when you gaze for your aura x
