Is it normal to imagine what it would be like if a family member died?

Sometimes I imagine that someone I love died. I think of the emptiness, the funeral, the family crying alone... It makes me cry, and my heart sink. What's even weirder is that I sometimes think of what would happen if I died. I imagine my family and relatives and how sad they would be and what they would say... That makes me cry too. Then I feel like being more careful lol. I do this every once in a while, but does anyone else have these thoughts?
