Most dreams are messages from the subconscious mind. Typically, you are just processing daily thoughts, feelings and events in the dream.
Foxes symbolize people who are clever and cunning and use trickery.
Death as a dream symbol indicates change, transition and transformation.
21 is a number used quite often in poker and gambling and usually is a good number for winning.
But 21 foxes are dead, and trickery, cunning and deceit/manipulation is not winning - if you have others around you like this, it will mean they are defeated and you are winning.
