Body Hair
Scholars have said that if one sees themselves pulling out their body hair, they may gain an increase in their worldly affairs. Any increase in the body, if taken away, may be interpreted similarly. It was also mentioned that if one's testicles are cut off, they may cease to have female children, and if one's male organ is cut off, they may cease to have male children.
