Grandpa loves his grandson most, but he did kill his grandson in his dream. In fact, killing a grandson can be understood as an accident. Accidentally injured, in real life, he should have seen other scenes that hurt children (in life or on TV), and dreams are just a manifestation of excessive concern.
It is suggested that dreamers should have a good attitude, don't worry too much, and impose unnecessary negative emotions on their hearts. I wouldn't have such a fierce dream!
This is a scientific dream interpretation!
