To dream of the Borg from Star Trek represents a dangerous conformist presence in your life. An aggressive desire for conformity that you feel never stops once it's given power. Feeling that you risk losing your independence forever to a pointless system or group. You may feel that someone or something wants total conformity with no consideration for other possibilities ever again. Your fear of assimilating into situations that destroy your individuality if you acknowledge them. Feeling that someone else's choices are both controlling and unbearable.
You or someone else that wants to stamp out all diversity while spreading conformist ideas or values. It may also reflect a very aggressive and ambitious desire to for total conformity.
Example: A man dreamed fighting the Borg. In waking life he had avoided paying incomes taxes his whole life and finally faced the prospect of having to pay them. The Borg reflected his feelings about the government and paying taxes being an unbearable lifetime imposition on his independence that had to be resisted at all costs.
