When an obstacle appears in a dream, it presents you with an objective view of how you use the word ‘but’ as a roadblock. Whenever this word is used in a sentence, it negates the power of whatever preceded it. “I want to be healthy, but…” I know I should study tonight, but…” Obstacles present a tangible vehicle that allows you to understand how you get stuck. In the dream, you are attempting to do something, but there is an obstacle. Rather than see it as a roadblock, look at it for the opportunity to transform or integrate this symbol into what you are doing. If the obstacle is a tree, explore your roots; it is a police barricade, explore how you might be too strict with yourself.
