A relatively young belief that quickly gained popularity and remains relevant in the 21st century.
There are a number of theories about where this superstition comes from. The most popular explanation is that in a dream, a person resembles a dead person, so such a photo can bring death.
It all started in the 19th century. As soon as it became possible to take photographs, the wealthy classes developed a tradition of capturing a deceased relative as a keepsake. The deceased was seated at a table, a book or newspaper was put in their hands, and a photo was taken. In the pictures, the deceased resembled a person who had simply fallen asleep.
The tradition continued until the 1960s. Then the belief was born that you can’t photograph a sleeping person, otherwise you can bring death upon him.
According to esotericists, the soul of a sleeping person is the most vulnerable. In such pictures, a part of the soul and the energy flow of the photographed object are preserved.
This can be used by sorcerers or witches to cast a curse or damage. Therefore, psychics definitely do not recommend posting such photos on the Internet.
