Every day, entering the house on the doorstep, you have an old rag on which you rub the soles of your shoes! And day after day, these rags endure our pressure on them! Once I noticed that if you wipe your feet on a rag at the threshold of the house every day, then over time, images appear on this rag in the form of images of the face of the one who soaked his feet on it! I decided that this is something important in nature and this phenomenon needs to be studied! I came to the conclusion that energy is transmitted from a person to an object and objects around a person are able to remember this energy and over time it is shown in the form of images! It’s called existential energy exchange! Nature still presents us with many mysteries that mankind has to solve!
