When one feels as though they’re breaking apart, their body could be releasing toxins. In dreams, this symbolizes cleansing of the soul. One is able to experience self-awareness when they let go and allow for change.
In dreaming, the word “decompose” can best be translated to “breaking apart that is a process of healthy re-composition” or “peace through disintegration of illusions and ego fears.”
Images of breaking or falling apart as in decomposition are common components of dreams. Dreamers may encounter collapsing buildings, burning bridges and abruptly splitting families. There’s probably never been a psychological trouble quite like old age-related death anxiety, when people are grappling with the fact that they’re going to die and spend eternity apart from the family and friends they love.
Decomposition in dreams most often signifies a leap from one life stage to another – death for rebirth, break up for getting back together, etc. Any time you feel that “life is changing” is simply the starting point of another journey.
