Dream of child, grandpa

I had a recurring dream as a child that terrified me, this dream where I saw two of either my grandma or grandpa who were my parental guardians at the time, and everytime in the dream i would stand in between two of my grandmas and sometimes it would be two of my grandpas and each would try to convince me they were my real grandma or grandpa, it always felt terrifying but I would always wake up before i made a decision
