Acid – Acid is a corrosive substance, and in a dream it indicates a fear or feeling that something is eating away at you. It could indicate a relationship that you feel is being worn away by a corrosive influence. It could also indicate an emotion being eaten away, or your stability being corroded. A specific item being eaten by acid may indicate a problem you wish would just disappear. This is a very powerful symbol, but it must be taken in context with the rest of the dream to understand what it means.
