Cactus
To dream of a cactus represents feelings about behavior or a situation that thinks about why it's interesting to survive emptiness staying the way it is while it hurts you if you get too personal with it. Behavior that likes itself surviving emptiness the way it is and hurts you if you do anything except accept it. An individual or a situation that's interesting about staying the way it is in emptiness while being easily irritated, touchy, or difficult to deal with when you get too close and personal with them. Facing discomfort before learning how to move on from a situation. Situations that you feel are best left alone because you waste your time being close and personal with them. An individual or circumstance that's interesting about why it stays the same and can be "prickly" or difficult to engage with on a personal level.
Example: A woman dreamed of getting married to a cactus. In waking life, he was trying to commit herself to studying for her school exams for a course which she believed failure was an inevitability. She felt she looked stupid for even attempting to study the course material. In this case, being married to a cactus may have reflected her perception of her commitment to studying a failing course at school out of the interest of still potentially passing, while also feeling that going to class emotionally hurt her by feeling stupider than other people for getting too involved with it.
Example 2: A woman dreamed of feeling cactus thorns in her feet, but when she looked down it was a black lizard. In waking life, she was taking care of her elderly father-in-law who was very ill. In this case, the cactus thorns may have reflected her feelings about her elderly father-in-law being interesting to take care of because he is family and her deceased husband's father, while at the same time not liking to think of too much personal cost with time and money once his health problems became too serious.
