As with a lovely garden, beautiful trees are a favorable omen in a dream, and planting trees is especially auspicious for love affairs and/or matters of friendship.
Cutting down trees portends difficulties of your own making, and climbing a tree is one of the few exceptions to the “up is good” rule, as it indicates hard work for small gain.
Blossoming trees predict unexpected joy, and a row or line of trees indicates extended advancement Aspen signifies a season of loneliness; Crabapple a new experience; an Oak is a sign of faithful love; a Spruce promises good health.
To dream of tree stumps signifies changes and new beginnings.
