What the frig was that... moments.

Only 1 other time have I seen this type of thing in my lifetime.
I have no name for what it is. Perhaps it is a ghost in disguise.*grins*
But it is full of looming energy and moves like a shark in water.

First time I saw it was spring of last year at a flea market. A large open building, I was standing in an wildlife sketch artists booth when I caught something hovering 2' off the floor just outside his booth. It appeared to be a black blob, in an oval shape. Maybe 3' by 2' in size. Inside it's shape in moves in waves.

Second time I saw it was last fall, this time I was not so calm about it... it was following the same artist. *a unique man, a dwarf with long black hair in a tail* I was standing in my booth talking to a long time friend when I saw it following him about 5' behind. Weaving around the people in the crowd moving back and forth like a shark. Stretched out some with a trailing ass end. My friend didn't react to the artist passing behind him, but when this blob did, he shivered then closed his eyes and did a body shake turning white. All I could say was, "Holy *hit do you see that? Do you see it?!!" I ran out of my booth into the hallway, rubber leg syndrome taking over when I realized that "They" were headed directly down to where my baby sister works in the Candy booth. I watched numb until I realize the bathroom was the destination. I kept an .... Eye *grins* until he went back to his booth. My sis doesn't see and the feeling and pounding in my chest wasn't good.

So why do I bring this up now?
Because I have a strong feeling this blob is about again.
I had given things and a source of protection to this man last fall and his life settled and he was happier.
I see him every weekend but this weekend I picked up his darkness again. He looks tired and beaten down... drained and grubby.
Since I got home from work, as soon as my mind is at rest, this frigging blob enters my mind.

I believe that whatever this blob is, feeds off this poor man
I believe that it is back and I'm not really sure what it is, let alone why it's back and why it follows Him. Could it be part of the building and seeks him out each weekend? Or is it him.
Is it some sort of dark spirit/ghost? A type of negative energy that has the ability to do harm to one that walks the earth?

Any Ideas?
