So, can dreams carry messages from loved ones who have died?

According to Patrick McNamara, associate Professor of neurology and psychiatry at the Boston University School, there is a particular term for dreams about dead people – visitation dreams.

It means that the deceased person is visiting you in your dream, or as McNamara explains it: “Dreams of the bereaved where the dead appear to the bereaved in dreams and look to be very much alive.”

The 67-year-old neuroscientist is an active blogger at Psychology Today, under his alias, Dream Catcher. Over the years, McNamara has often shared his thoughts and findings about dreams and their meaning. And visitation dreams usually have a logical explanation, according to him.
