Garlic in a dream is ugly unlawful money and ugly praise. Eating it cooked indicates repentance from sins. Eating it raw indicates consuming unlawful money or backbiting and gossip.

Garlic indicates worry, grief, sadness, and crying. Uprooting it from the ground indicates harm afflicting the dreamer from his relatives. For the sick, it is recovery.

Garlic is interpreted as unlawful money and bad speech. Whoever sees himself eating garlic, people will insult and blame him because of his greed.
