The Pig
Scholars have said that whoever sees themselves walking like a pig might achieve swift joy. Eating cooked or roasted pork may indicate ill-gotten gains quickly acquired. Ibn Sirin interpreted seeing a female pig on one's bed as cohabiting with a disbelieving woman, and a story is mentioned about a king's dream interpretation where a pig symbolized a man sharing his women.
Per Ibn Sirin's Muntakhab al-Kalam fi Tafsir al-Ahlam
