Severing the Gallbladder
Scholars have said that if one sees a person severing another's gallbladder with their teeth and causing death, it may indicate intense malice from the aggressor that leads to the victim's ruin. It was also mentioned that a healthy lung might signify a long life, and a diseased one a shorter life, and the kidneys may refer to wealth, children, and relatives.
