Unknown 
To dream of someone unknown to you denotes a part of your own self that is concealed and subdued. Then again, it may symbolize the archetype dream helper who often tries to offer some counsel and insight.
Blind Date
Going on a blind date in a dream suggests taking a risk, whether romantically or otherwise. If your date does not show up and you are left alone at a restaurant or in front of a location, it symbolizes your fear of being alone or of being rejected, especially by those that judge you from afar.
