Ghosts are the main killers. Ghosts represent bad things, which is ominous. If you dream of ghosts, you will be in danger. Be careful that the little people in your life set you up. You and your mother drive away, don't be afraid. This indicates that you will overcome the disaster.
But I think you dream of a lot of cobwebs in grandpa's house. You'd better go to his grave to pay homage. If the grave is damaged, repair it as soon as possible! ! ! !
This is just my personal opinion. I hope it works for you.
