Good Day, one of the Nobles!

I have just one event that took place a month ago.
Might you have any explanation to what i was met with?

So. I was at my parent's house in a suburban area,
smoking a cigarette in the backyard, it was dark already.
Out of a sudden a ball of golden light energy,
the size of a fist appeared hovering mid-air,
in the middle of our backyard and started making few meter long loops in the air, back and forth and the wind went with it, but only to a set 5 meters radius of a cube from it
and waved about our apple trees, like it was having a lot of fun.

Then it stopped 2 meters away from me, materialized into this deep purple skinned alien, golden straight hair with large, sad eyes and robes covering it that seemed to have been woven from some kind of noble metal/silk.

It bowed to me and walked two steps towards me, before vanishing away. "She" was about 1,6 meters tall.

Where was that visitor from and why did it come to pay respects to me?

I have been practicing witchcraft for 19 years.
I am not from a noble bloodline.

ANY IDEA ON THIS?

ALSO WHAT DO YOU DIG ABOUT THIS SIGIL I MADE?
IT IS SUPPOSED TO BE USED IN CONTROL RITUALS.
