Born a slave in Dorchester County, Maryland , Tubman was beaten and whipped by her various masters as a child . Early in life , she suffered a traumatic head wound when an irate slave owner threw a heavy metal weight intending to hit another slave and hit her instead. The injury caused dizziness, pain, and spells of hypersomnia, which occurred throughout her life . She was a devout Christian and experienced strange visions and vivid dreams, which she ascribed to premonitions from God.
