Mistletoe
A plant that grows on the branches of trees rather than in the ground — a sacred parasite kept for ritual.
Mistletoe in a dream is the dream's image of a plant that does not stand on its own ground. The mistletoe lives in the branches of an oak or apple and draws on the tree that hosts it; old traditions hold the plant sacred precisely because it grows where no plant is expected. The dream brings mistletoe when something in your life — a friendship that lives only inside a shared workplace, a ritual that only happens at someone else's house, a piece of yourself that exists only in another person's company — is a real growth that has no ground of its own. A sprig cut at the right season is the dream affirming that the borrowed growth has its proper use. A mistletoe so heavy that the host branch is dying under it is the dream noting that the borrowed life has begun to cost the host more than the host can carry.
