As you go up in the elevator in your dream or vision, you are telling that you have reached a higher level of consciousness in your life, you have grown inwardly and are rising above yourself. Another explanation is that you experience new opportunities and possibilities or perhaps prestige or wealth.
Yet another explanation is that you experience an imbalance between your male and female energy or at work, at home, in relationships and feelings, you have to learn to ground and find the balance. An alternative explanation is that you feel somewhat exalted, bigger than you really are or that you consider yourself above other people.
When you go down the elevator it tells you about the longing for the past, the unresolved obstacles, problems, fears, anger, pain and sorrow must be solved and explored before you can continue in life.
The up and down movement of the elevator tells you the ups and downs of life that are needed to grow in a process or in life itself. An alternative explanation is that bad luck is going to surprise you; it discourages you from doing things.
An elevator that goes from left to right in your dream or vision tells you that you are going in a different direction in your life, you have made a choice or you are going to make a choice that will leave your current life path. This can be either positive or negative.
