Redwood
To dream of redwood trees represents longevity or something you can't believe will ever go away.
Negatively, a redwood tree may reflect problems that you think are too big to ever go away.
Example: A woman dreamed of seeing two redwood trees in the forest that she felt were symbols for her and her husband. In waking life she was having doubts about whether or not her relationship would last. After 14 years she and her husband were still together.
