Dreams dictionary: Cactus

Dreams dictionary: Interpretation 1
To see a Cactus in your fantasy proposes that you are feeling attacked, that your space is being packed into and that you are feeling choked. The thorny spines of the desert plant speak to your desire to build up a limit of your own space and security. You have to safeguard yourself somehow. On the other hand, the fantasy infers that you have ended up in a tight spot. Maybe you have to adjust to your current conditions as opposed to attempting to change them."
