When this woman is concerned about her sister, she asks Reddit:
My sister has been depressed for a long while and one thing I know she has always found some comfort in is spirituality. No specific religion, but spirituality as a whole. Energy, universe, vibration and psychic stuff.
A few days ago she went to a medium. She was told that our grandfather is speaking to her, and this medium did say some things that could ring true for our culture (we're born and raised in northern Europe but with a different ethnic and cultural background).
Our grandfather apparently told her stuff about how we should be as a family, how our virtues and values should be like and how we should pursure our future.
To make it more believable, my "grandfather" said some stuff that are specific to our culture, which convinced my sister even more that it is true.
