To dream about a dead sibling, another relative, or an acquaintance, suggests that you are longing for them and attempting to revive the times you shared. As you move through life, dreams offer an opportunity to deal with issues involving loss and grieving.
To see and talk with your dead parents in your dreams, represent your fears of losing them or your way of coping with the loss. You are using your dream as a last opportunity to say your final good-byes to them.
Me: if i was you i would be scared and creeped out too. If your Papi (grandpa) actually came to your dreams, i think he was just jocking around with you or he really wanted to know (which i think he already knows).
