What is it like to dream that a loved one who just died burns incense for himself?

According to superstition, grandma came with a dream the next day without burning incense for her. In fact, because you miss your grandmother very much, you think about it every day and dream at night, so whether you are superstitious or not, you can burn incense for your grandmother. On the one hand, it is to alleviate the feelings of missing, on the other hand, it can be regarded as filial piety.
