Welcome to intro class and to DV, AquaBlitz11!

About dream signs, have you considered looking at broader categories like people, places, certain items, situations emotions? If your dreams have "unknown people" in them then this might as well be called a dream sign. To be able to catch such a dream sign, for example, try asking yourself during the day - who is this person, who do I know them. If it's a dream, it may be the case that a DC just came out of nowhere and is now playing whatever role you have assigned them. So, always be on the lookout and questioning. What am I doing? Where am I? Who is this?
