Dreams of walking on broken glass, seeing or being surrounded by shards of glass or, even worse (and far from everyday), having to eat broken glass may represent cutting words or wounding experiences. The vivid image in the dream is designed to draw your attention to a pain that you may have been denying in waking life. It can also refer to something clear and pure that has been broken, suggesting the shattering of expectations. Typically, such dreams are linked to personal, rather than career, conflicts.
If you have such a dream, has something in your waking life changed dramatically and has that change caused you pain? If you are eating the glass, this suggests that you are taking in the painful experience, but it may be asked whether you are trying to swallow rather than acknowledge your pain.
If you are walking on glass, consider how your direction in life is causing you pain.
