[Brown Eyed Mystic]

A physical person could have sent you a nightmare either to harm you or to teach you. I did this once to somebody when I learned that this person was going to try and bring forth a demon as part of an occult self initiation. I sent this person a nightmare to show him what could happen if he did bring forth this demon. Later I found out I was successful, he had the nightmare, and changed his mind.

Now that is something.
