Answer:
The phrase "The disasters numb within us caught in the chest, rolling in the brain like pebbles" suggests a sense of overwhelming emotional or mental burden caused by past traumas or tragedies. The word "disasters" refers to these traumatic events, which are said to be "numb within us," implying that the pain is still present but perhaps repressed or difficult to access. The phrase "caught in the chest" suggests a physical manifestation of emotional pain, such as tightness or heaviness in the chest. The metaphor of the disasters "rolling in the brain like pebbles" suggests that these memories are constantly present and can be triggered by even small or insignificant events, like the movement of pebbles. Overall, the phrase suggests a sense of emotional weight and difficulty in processing or moving on from past traumas.
