psychic light- what is it??

[samsara]

Hiya,
Can anyone help. I have been attuned to reiki 1+2 and after the first attunment I see a light in the sides of my vision field which wasn't there before. I can only generally see it if my room is dark and if I close my eyes and rotate my head left to right I can see a light effect similar to waving a light source in the dark. I can also make this light grow brighter by meditating or relaxing. Is this the beginning of auric vision because I cannot see light around other objects or people, only around my head.
