Hi OMJ,
A couple more things I wish to ask you:
Have you witnessed such visual phenomena before?
Is there anything you could be doing to attract this thing into your space? Focusing your intent on a subject will certainly help to magnetise and bring it closer to you( whether you are using intentionality or unintentionality).
I have to say it does not seem like a being from the light, by the way you describe it and how it makes you feel.
