Have you ever tried pushing your eyeballs in? I press them firmly in and I begin it see colors like red, blue, and green and other colors even though in my room it was pitch black where no light could come in.
Once I held and gazed for awhile, I started seeing a tunnel that changed colors every now and then, but it was constant. I then started to see a static screen and all of a sudden, the screen turned on!
I saw some random country which I am thinking was the Netherlands. It was basically like seeing it with my own eyes what was there, but wasn’t physically there. I encourage you to try it so you know what it looks like and put some feedback here.
