In Destiny 2 when a Guardian is resurrected for the first time, they have no memory of who they were before, and are commonly called "New Lights"

This is the art I made of her when she was fresh out of the grave, having just been resurrected for the first time very recently. Her Ghost's name is Flower, since her own name is from the white Curii flower that was native to the eliksni homeworld of Riis. (this flower lore is literally just my headcannon because I thought it was a neat tie in, dont' @ me)
