Laura – Well, take what I say with reserve.
This is because the dream appears to suggest that your sister in law is following your dead friend. In other words she could die.
But as I have said to others, it doesn’t mean it will come about. Things can be changed by the good will and loving thoughts of others and the person themselves. So ask for help for your sister in law. Visualise her surviving any near brushes with death, and ask for help from whatever you believe in that has power.
I am holding a wonderful umbrella - huge like a parasol. It is to shield others from harm.
