To dream that people or objects are disappearing before your eyes, signifies your anxiety and insecurities over the notion that loved ones might leave your life. You may feel that you cannot depend on someone or that you are all alone. You need to work on improving your self-esteem.
If you dream that you are disappearing, this suggests that the way you have been acting is out of touch with your true values.
1. Serious insecurities, usually involving loved ones, sometimes material possessions.
2. Reverse: money or possessions will come easily.
3. Unreliability, usually of an individual.
To dream of something suddenly disappears represents that you feel that something is missing in your life. Also, you are coming to terms with impermanence, change, and the illusive, mysterious nature of life.
