Are there one or more animals that you have found elicit a negative response? Do you feel afraid or just uneasy around them? If you have a phobia in particular it may be a sign that the animal you fear is a "shadow totem". Shadow totems of course also serve a purpose - to help you deal with and conquer fears and work through different life challenges.
How to Discover your Shadow Totem
For this exercise you want to relax and close your eyes in a place where you feel comfortable and know you are safe. Take some deep breaths and relax as deeply as possible and as you become more relaxed, picture a heavy wooden door in front of you. Behind this door is a glass screen that you can see through. Knowing that your animal is encased in the glass will allow you to feel safe enough to open the door and see what lies behind it. When you feel ready, open the door and what you see there will be your shadow totem. If this exercise doesn't work the first few times, don't give up on it.
