agreements, threats and curses are made by the human’s soul essence, not by the biology. Soul contracts are made and held in higher frequencies than the third and lower fourth dimension. In higher frequencies there is no time, space or place. That means contracts remain in effect regardless of the container or form the soul essence is in. If a soul essence vows to “ALWAYS protect another” that remains in effect until one or both parties end it. Vows can be made many, incarnations ago and still be honored.
The soul essence living in Egypt, during the ninth century could have cursed you or vowed to love you always, and may be your neighbor now. BUT neither of you would have conscious memory of it. Your higher self or stream of consciousness would have awareness of the contract. Just ask!
The soul essence you have contracts with could be in a human now on earth OR in a form on another planet OR be an astral body in the fourth dimension. Because the 3D human container’s lifespan is so short and entering a new container frequently means ignorance of all the soul knows, the 3D human frequently is unable to remember these contracts. But the 3D human does get a sense or “knowingness” about another 3D human they interacted intimately with or know. They know there is SOMTHING between them, but they don’t know what.
