grandma's psychic dreams

my grandma has psychic dreams about people's passing. a couple years ago the night before my grandpa passed away my grandma saw him in a dream (basically of him in "heaven"). the next morning we learned that he had passed in his sleep. more recently my grandma told us he saw a boy with my grandpa in heaven in her dream. then we learned that her son had passed away alone at his home the same day she saw the dream (she had no way knowing it, none of us did. his passing was unexpected unlike my grandpa who had cancer and had a deteriorating condition). my parents say that my grandma has had such dreams before about her mother and some other people in her life.

i'm honestly not a religious person at all but it's a bit eerie to me and i don't have an explanation for this. idk i just wanted to ask if others have such experiences?
