Dream About Seeing Grandad And Great Grandad Die In Tsunami

Seeing my grandad and great grandad die in a tsunami, and trying to save him,after jumping in the water to save them , then being at my dad's who was alive again and my partner had made him a book of his past and of him with his dad and grandad, the book was of old pictures and notes , of his past with his dad and grandad on , and asking him if he knows who they are ,he smiles and nods and crys when he sees his dad and grandad which make me cry just seeing a tear roll down his cheek
