To see a fox in your dream represents insight, cleverness, cunningness and resourcefulness. Perhaps the dream is telling you that you need to exhibit more of these qualities in your waking life. Or that you need to conceal your thoughts and be more discrete about some situation. The fox may also symbolise someone in your waking life who is sly and sneaky. Alternatively, seeing a fox in your dream indicates a period of isolation or loneliness. You need to take this time to ponder some issue or reflect upon your life. The dream could be a metaphor for someone who is a “fox”, as in a foxy lady. 

To dream that a fox is flying into your window means that you need to be careful with who you trust. Someone in your waking life is up to no good.
