If you dream of calomel, be wary — someone in your life is working against you, and they may be doing so through people you consider allies. Your friends aren't necessarily complicit, but their unwitting involvement makes the betrayal harder to see coming.
For a young woman, dreaming of ingesting calomel suggests she may find herself manipulated by those she places her confidence in. The people she trusts most could be the very ones whose calculated motives lead to her harm.
If the calomel appears applied to the skin rather than taken internally, it points to a different kind of self-deception: a conscious choice to look away from warning signs. The pleasure of the moment feels worth the cost — but only for a time.
