You feel repulsion because you are a genuine abductee. The image dredges up horrifying memories from your subconscious. You've not only been taken once, but all through your life, starting from early childhood.
The greys (led by their masters, the reptilians) have intruded upon your life, appearing in the dead of night, or when you were far from human help, terrifying you no end.
They have taken you aboard their ships, and have conducted the most heinous acts upon you, such as removing all forms of tissue samples, inserting strange devices into your body, sometimes removing, then replacing your eyes from their sockets, and placing implants in your nose and/or leg.
You have been used to create human/alien hybrid creatures for some sinister purpose that only they know about.
Your mind has been probe, and you have divulged to them all that you have ever learned or experienced in your life. And, once this has been done, your mind has been erased over and over, like some old VHS cassette.
They own you, and there is nothing you can ever do about it!
Well...
That's what a believer in alien abductions would say.
Personally, I think you're just making too much out of it. Relax, it's only a distorted human face someone made up.
