To dream – means ship fragments that soon some ship will crash or great accident will fall upon many people. If you dreamed fragments of any building, – you are expected by ruin and grief.
A piece, fragment, sliver, etc. might represent:
Part of a whole (such as one member of a group, or one event in a series)
The idea of small, or a miniature version of the whole
Disintegration (in the case of an object that is breaking or eroding)
The idea of "not enough" or feeling short-changed
