The Testicles
Scholars have said that seeing the testicles in a dream has several interpretations; if they are cut off without decay or harm, it may indicate that enemies will triumph over the dreamer to the extent of the harm inflicted on his testicles. However, if they are large or possess strength beyond their normal size, it suggests that enemies will not be able to harm him. Their severance might also signify the cessation of female offspring if other elements in the dream point to good. If the testicles are in the hand of a known man, that man will overcome the dreamer, and if the man is young, he is an enemy.
