Here's why:
* Metaphor: A metaphor directly compares two unlike things without using "like" or "as." In this case, it's comparing a person's state of being to being trapped within a block of ice.
* Meaning: This metaphor likely suggests a feeling of being trapped, frozen, or unable to move or express oneself. It could also imply a sense of coldness, detachment, or numbness.
