Wear a blindfold (like the Mindfold), and try to detect what is being displayed on the screen with sustained intentioned focused awareness.
Random Color Detection between two colors - There are three colors, Red, Blue and Green, but because these tools are designed to not show you the same item twice in a row, this means that beyond the first round, you will effectively have only two possible choices, the two remaining colors. For example if the current color is blue, the next color can only be either green or red.
Press space bar to speak the name of the color. A few seconds later, a beep sound will indicate that a new color is displayed.
Random colored triangles in a 3x3 grid Detection - Press spacebar or click LMB to speak a description of what is being displayed. When you press the key a second time, it will randomize the triangles and colors, and play a beep sound to indicate that it is ready.
You can also use this as a visualization exercise : if you need the description to be spoken again, press Enter key on the alphanumeric keyboard. This will vocalize again as many times as you need, without randomizing the triangles.
Shape animation - With this one, simply stare and try to detect movement and color
Random Color Detection - Same as the first tool but now there are several more colors involved. Press space bar to speak the name of the color. A few seconds later, a beep sound will indicate that a new color is displayed.
Number Seeing Training (White) - Press space bar or click LMB to speak the number. Press space bar or LMB again to display a new random number, a beep sound will be heard. Press Enter key on alphanumeric keyboard to animate the number a bit, which could help you detect the number.
Number Seeing Training (White)2 - Press space bar or click LMB to speak the number. After a few seconds, a beep sound will be heard when a new number is ready for detection.
Random shape detextion - Press space bar or LMB to speak the name of the shape. A beep will sound when a new shape is displayed for detection.
Letter seeing training - Press spacebar or LMB to speak the letter, press again to select a new random letter.
Here is a playlist of videos to inspire you, and guide you.
Try the experiment from the first video. If you are among the 50% of people who don't detect their hands at all in the dark, just keep trying. Don't force it, just try now and then, let it come. Be patient, but you need expectation. Whenever you give it a try, intend and expect to see your hands in the dark.
If you are among the 50% who see something right away, that's a great start. There is nothing unusual about it, it is a form of synesthesia. Now, take it further, play with it. Wear the mask for prolonged periods, to perform tasks, maybe move around cautiously in a safe environment. I bet you will start detecting other things, not just your hands. You will detect variations in shadows, walls, doors, furniture ? Now that is weird and wonderful, isn't it ? Maybe you will want to continue exploring the possibilities.
Now you are entering a new paradigm...
Watch the other videos in the playlist to explore your consciousness in a new way.
