A Man Marrying Another Man
Scholars have stated that if one dreams of marrying an unknown man who is young, it might indicate the dreamer overcoming an enemy. If the man married is known and there is a dispute between them, the dreamer will prevail over him. If the man married is an unknown elder, it might signify good reaching his grandfather from the dreamer. Similarly, kissing, sleeping with, or mingling without desire between two men indicates meanings similar to marriage but with less intensity.
