Dream interpretation : Cactus

Dreaming of a cactus is usually the indication that you are feeling crowded, or that someone is invading your space, and since the cactus has the prickly spines for defense this represents to the dreamer a wish to establish a boundary and protect your privacy. Thus, to see a cactus in your dream, suggests that you are feeling invaded. Your space is being crowded into and you feel like you are being suffocated.  The prickly spines of the cactus represents your wish to establish a boundary of your personal space and privacy. Perhaps you have found yourself in a sticky situation. Alternatively, a cactus may be symbolic of your need to defend yourself in some way.

A cactus also represents winning out over adversity as it is found in the desert and has adapted itself to hot, dry, growing conditions, thus to see a cactus in your dream can also signify your need to adapt your existing circumstances instead of trying to change them.
