Oak tree
A slow, massive tree of long-lived strength — endurance built across generations.
An oak tree in a dream is the dream's image of strength that was not produced by you and will not finish in your lifetime. Oaks grow slowly, last for centuries, and become landmarks for everything around them. The dream brings the oak when something in your life — a family, an institution, a piece of land, a long marriage — is operating on a timescale much larger than your own. A standing oak is the dream telling you the larger structure is intact and supporting you. An oak being felled is the dream marking the end of something that was supposed to outlast you, and the suddenness of the loss is part of its meaning.
