Since I was a small child my mother would comment on her dreams or on our dreams and give her opinion on certain ones. She was not necessarily a believer in dreams, or zodiac or any superstition. However, if I or anyone else ever said they had a dream about someone that had already died, my mother would say they need prayers. The dream about someone dying signified that there would be a birth and likewise if you had a dream that someone was going to have a baby that meant someone would die. The information was relayed as simply that the possibility of this meaning was there. My mother now 80 years old lives with me and she had a dream about her aunt that passed over 30 years ago. Her response was " why is she coming to me in my sleep now? I hope that she is alright and that she is with God."
