When Harriet Tubman was approximately 13 years old, she suffered a catastrophic and life-altering head injury while standing her ground in a dry goods store. An overseer was attempting to stop a runaway enslaved person and threw a two-pound metal weight, intending to hit the fugitive. Instead, the weight struck Tubman squarely in the forehead, crushing part of her skull. She was left without medical care for days and was forced back into the fields while still bleeding and semi-conscious. This injury caused her to suffer from seizures, severe headaches, and "sleeping spells" (now believed to be narcolepsy or temporal lobe epilepsy) for the rest of her life. Paradoxically, she interpreted the vivid dreams and hallucinations she experienced during these spells as divine revelations, which fueled her spiritual resolve and courage in leading hundreds to freedom.
