She suffered a severe head injury as an adolescent

It ought to have been a simple task. It is one of the interesting facts about Harriet Tubman. On his way to a dry goods store on a mission, Tubman bumped upon another slave there - a runaway who had escaped his plantation without authorization.

A defiant Tubman declined to assist in the slave's restraint when the overseer ordered it. The supervisor grabbed a two-pound weight off the counter and tossed it at the fleeing man, but it missed and struck Harriet in the head with a terrible blow. It took her a long time to recover from this, and it has left her prone to episodes of lethargy or stupor that sometimes overtake her in the middle of a discussion or other activity and send her into a deep sleep. She will soon wake up and resume her work or conversation.

Instead, Harriet was hit, and she said it "shattered my head." She had convulsions, chronic headaches, and vivid nightmares. Tubman viewed the visions as divine revelations, which informed her intense religion and fervent faith and served as a source of inspiration for her numerous rescue missions that saw her leading other slaves to freedom.
