The dream, in which you see the cactus, represents the feeling of intrude. Perhaps you do not have enough time and expansion for your individual growth. You find it hard to be who you are, because of the lack of independence. The bigger the spines of the cactus, the bigger necessity for freedom is required. Alternatively, the dream about cactus could indicate the way you are protecting yourself from those that can do harm to you. The cactus could also indicate the temporary disputes and negative feelings that will stay only for short period of time.
