If the icon featured a portrait of a saint or other religious figure, find out what tradition is associated with that person.
For example, if the saint was St. Christopher, then you may be on your way to taking a long journey.
If the saint was St. Jude, something wonderful and totally unexpected will happen.
If the portrait was of the Virgin Mary, someone will intercede for you in a disagreement and put it to an end.
Icons in general seem to bring a message that coming changes in your life, however stressful they may be, are beneficial and can be dealt with fairly easily.
