Spiritual Meaning:
Spiritually the cauldron symbolizes renewal and rebirth. Many folk tales use the symbolism of cooking to represent the making of mankind. A cauldron can also represent the womb.

Psychological / Emotional Perspective:
Psychologically, when a cauldron appears in a dream we may need to take note of our intuitive abilities, or of our ability to create new things from simple ingredients.

Everyday Material Aspects:
Almost universally the cauldron represents abundance, sustenance and nourishment. By association, the magic cauldron suggests fertility and the feminine power of transformation. To dream of a cauldron, therefore, reconnects us with our basic principles.

Gender / Specific Meanings:
Originally the cauldron was round-bottomed, thus reinforcing the symbolism of the womb. In a woman’s dream it therefore suggests transformation often brought about by her own power. In a man’s dream he is more likely to use power beyond himself.
