The Ram
Scholars have said that seeing one's body transformed into a ram's body in a dream may indicate the manifestation of generosity and fairness from the dreamer. If the dreamer has a ram's tail (اليه) which he licks with his tongue, he might be blessed with a prosperous child from whom the dreamer will benefit.
