Are Dreams of Dead Relatives Real?

Can we have dreams of dead relatives? Walter Veith explains the state of the dead as described by Jesus and the Scriptures. Hear about how the dead do not have any cognitive function and are unable to communicate with us. The Scriptures explain that those who have passed away do not know anything, and they have no share in what occurs under the sun. If it is not our dead relatives, then do the Scriptures shed light on who is actually appearing to some people in dreams and in visions?
