If you dream that you are disappearing, it may indicate a long journey ahead. Such dreams often symbolize the beginning of a new chapter or a change in your life. You might be moving towards new relationships or a different lifestyle. In this situation, you may feel the need to distance yourself a bit from your current circumstances, which could open doors to new opportunities for you.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Disappearing" (page 119).
If one disappears from his house or from the country, and if his tracks could not be located in the dream, it means taking a long journey, turning out to be where he is suspected to be, getting married in that place, falling in love with an unknown person, falling sick in a foreign land, or it could mean death ifthe person is sick. However the disappearance of God's loving people in a dream perhaps means thinking about one's beloved, or being exposed to uncommon mysteries of the universe. If one disappears within the earth without going through a hole in his dream, and ifhe remains a long time therein until people think that he will never come out again in the dream, it means self-deception, arrogance and love for the wor ld, and such a person will die in that pursuit as a consequence of adven turing with his own life.
