Observation-Ghost and the Supernatural is a reoccurring motif in Beloved, and reflects slavery in the 1800's because many slaves were not given proper burials and didn't have the chance to live their lives. This lead to superstitious beliefs that their ghost haunted the earth because of unfinished business.
Conclusion-Beloved was just a child when murdered by her mother Sethe. She wasn't given the chance to live her life and be loved. Therefor, she roamed 124 awaiting until she could come back to earth and receive what she missed out on. A childhood and most importantly her mother's love. Similar to Beloved, the slaves who were killed were believed to cause chaos and mysterious events because of their anger.
Do you feel Beloved haunted 124 because she missed out on Sethe's love? Or did she haunt the house because of anger?
