Herpes
To dream of herpes represents a pleasant situation that has turned bad and permanently requires constant care. Having to keep managing the consequences of a disappointment. Alternatively, herpes may reflect a tragedy that never goes away.
Herpes in a dream may be a sign that you need to let go of something or move in a new direction. You may be managing a failure because you can't except that it's over.
Example: A man dreamed that his best friend caught herpes. In waking life his attempt to improve his business with a new opportunity turned into a giant failure. He felt trapped into having to manage the increasing costs in order to stay in business.
