Cheating means you miss your grandparents, but you know they are dead, so you cheat. If you don't know that they are dead, then they are people.
Because cheating is not a person, you have seen horror movies, derailed bodies eat children, kill people and so on, so taking children away is your plot.
Because you don't want your grandparents to feel uneasy, and you don't want them to hurt people and be reviled and attacked, you think they'd better be buried!
But after all, faking a corpse is not a person, and there is no person's mind. You will naturally think of fear, whether they will attack you, and then your sight will change and you will be blocked ~ ~
That's all.
Remember: dreams come from the heart.
When you master it, you will like dreams. He can dream impossible dreams in the world, fly by magic and do anything.
