Borg
To dream of the Borg from Star Trek represents a dangerous conformist presence in your life that wants to assimilate you. Feelings about losing individuality to a powerful system, mindset, or group that demands total conformity. Evil in your life that you feel is aggressive about desiring perfect conformity that you feel will 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 your happiness 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. Negative behavior that wants to stamp out all diversity while spreading conformist ideas or values.
Additionally, the Borg could represent fear of being controlled, assimilated, or emotionally erased. Loss of free will, suppression of personal desires, or anxiety about becoming emotionally numb, robotic, or disconnected from your authentic self.
Example: A man dreamed of fighting the Borg. In waking life, he had avoided paying income taxes his whole life and finally faced the prospect of having to pay them. In this case, the Borg reflected his feelings about the government and paying taxes being an unbearable lifetime imposition on his independence with system assimilation that had to be resisted at all costs.
