My mother told me she had a dream about her brother in law who has been deceased for many years and that he was driving a car going 60 miles an hour and that he hit a sign and it split.And that my aunt his wife that has also been dead many years as well.She or my mom,my mom who is alive said,for him to slow down before he causes an accident.Only for her to receive a call this morning from my sister stating my niece was in a school bus accident.My mom dreams about dead people more then living people.And I don’t know what this means,she says they come to warn or help her.In the dream they conversate.Can someone give the interpretation please thank you
