In Margaret Atwood's "Lady Oracle," the metaphor of "vampire sheep" suggests a sense of passive danger lurking behind an innocent facade. This description portrays a feeling of being drained or consumed, highlighting the complexities of identity and societal expectations. The imagery evokes a contrast between the seemingly harmless appearance of sheep and the predatory nature implied by being likened to vampires.

The phrase speaks to the subtle threats that can exist in everyday life, suggesting that what appears benign can also be deeply threatening. Atwood skillfully explores themes of conformity, self-identity, and the challenges of navigating personal truths amidst societal pressures. This juxtaposition invites readers to reflect on the darker undercurrents that persist beneath a calm exterior.
