Specific trees may be significant to you, so try and identify the feelings and associations a specific tree evokes if one appears in your dream. For example, does the magnolia that graced your childhood garden conjure up a happy childhood memory or is it the tree you carved your initials on with the name of your first sweetheart? If your dream tree reminded you of nothing in particular, it may be that you are unconsciously aware of its traditional, mythical or religious symbolism and this may have relevance to your waking situation. Specific trees carry with them ancient associations and although it is unlikely that these association have much relevance in modern urban life, they can and do still carry weight in your dreams.
If you believe a tree in your dream was significant but you have no idea why, the following guidelines might help you; if your species of tree is not listed here, it may be worthwhile researching its traditional meaning.
