That’s an optical illusion I agree about it, what I’m talking about isn’t an optical illusion, it’s about the key to access to a 6th sense. It’s not about something you look with your eyes it’s about something you look with your brain.
If you are in a complete dark room what you see?
The eyes trick it’s just the way to make the brain telepathy work.
Or at least it’s what I understand of this, you should try it just to find out if it work for you or not.
