Harriet’s desire for justice became apparent at age 12 when she spotted an overseer about to throw a heavy weight at a fugitive slave. Harriet stepped between the slave and the overseer—the weight struck her head.
She later said about the incident, “The weight broke my skull … They carried me to the house all bleeding and fainting. I had no bed, no place to lie down on at all, and they laid me on the seat of the loom, and I stayed there all day and the next.”
Harriet’s good deed left her with headaches and narcolepsy the rest of her life, causing her to fall into a deep sleep at random. She also started having vivid dreams and hallucinations which she often claimed were religious visions (she was a staunch Christian). Her infirmity made her unattractive to potential slave buyers and renters.
