What Does Dreaming of an Onion Mean?
Traditional Interpretation
In the tradition of Ibn Sirin and al-Nabulsi, the onion mostly points to wealth that is unlawful or obtained in haste; its sharp smell can signify a period in which the dreamer should watch their tongue and their words. Seeing cooked onion is regarded as the herald of comfort and blessing that will follow difficulties, while raw onion can point to harsh words, gossip, or a passing sorrow.
Psychological View
In modern psychology, the layered structure of the onion suggests that the subconscious is pointing to hidden feelings and memories peeled away layer by layer; seeing an onion in a dream may reflect the dreamer's need to part the masks that protect them and reach their core. The tears the onion brings can indicate that a suppressed emotion is ready to come to the surface, and that you are ready for a process of inner cleansing and relief.
