One day, the adolescent Tubman was sent to a dry-goods store for supplies. There she met a slave owned by another family. That slave had left the fields without permission. His overseer was angry. He demanded that Tubman help restrain the young man. Tubman refused. As the slave ran away, the overseer threw a two-pound weight at him. The weight hit Tubman instead. Tubman said the weight "broke my skull". She later explained her belief that her hair – which "had never been combed and ... stood out like a bushel basket" – might have saved her life. Bleeding and unconscious, Tubman was returned to her owner's house and laid on the seat of a loom. She had no medical care for two days. She was sent back into the fields, "with blood and sweat rolling down my face until I couldn't see." Her boss returned her to Brodess, who tried unsuccessfully to sell her. She began having seizures and seemed to fall unconscious. She later said she was aware of her surroundings while appearing to be asleep. These episodes were alarming to her family. They couldn't wake her when she fell asleep suddenly and without warning. This condition remained with Tubman for the rest of her life. Larson suggests she may have suffered from temporal lobe epilepsy because of the injury.
