Dream is a powerful gift of nature unto the spiritually privileged by which messages from the unseen world are conveyed to us. It is a channel through which we receive messages from our ancestors. This channel connects us to the spiritual realm where we all came from. It gives us direct access to important messages that ordinary person is not privileged to receive.
But like i said above, only the privileged have this special gift of message filled dreams. But not all dreams are termed messages from the ancestors. Sometimes dreams are formed based on our activities during the day or through what goes on in our minds. Our focus is on dreams spiritually induced by our ancestors in order to relay or pass across a message to us.
