These changes are about vibration frequencies too. Reptilians and other shifters work on the same principle.
Children and animals have a different preceptive anchoring, therefore they are able to see real forms (even at the moment of transformation). Adults are indoctrinated with a matter-centered system and their preceptive anchoring is shifted, therefore they only see the final false result of the transformation.
Each color has its own vibrational frequency. A few years ago I talked about this with a girl who was born blind. I put objects of different colors in her hand and she never got confused once. She guessed the color every time and even the hue/saturation a few times. She described each color and how she felt these vibration frequencies. The color black really evokes sadness and warm colors (yellow, orange, red,...) warm, she said. And many other interesting things.

Perceptive anchoring -- that's a great descriptive term . How children and animals respond to someone reveals that person's nature. For example, It was most evident with the real Biden; in video after video, the moment he walked up to a child, that child instinctively pulled away. The queen also, same thing. Most adults were fooled, but not the kids.

I have also watched testimonies of people who have had NDEs. They say 'that side' is more real than this; and that there are millions of colors, with the colors being musical 🎶.

My dad's wife was a lovely person and lived into her 90s. She told me of sitting by her previous husband's bedside as he lay dying; he suddenly turned to her and said, "If you could see what I see; if you could just see what I see!" Then he closed his eyes and was gone ✨.
