How to find my spirit ani

At most? As many as people can imagine. You dreamed of a few, but any given mythology will have dozens, hundreds, thousands of different types of spiritual creatures. It all depends on what mythology you are following and your own personal beliefs.

the best way to find out what your spirit animal / totem animal might be
have a talk to your parents,
did you ever have an imaginary friend as a child that was an animal? its much more common than you think

I normally get wierd dreams of animals. Does that mean they are my spirit animal?

My spirit animal came to me through meditation

Whenever I felt stressed or threatened, I always noticed my spirit animal--an axolotl--nearby.

I have been seeing a walrus in my dreams for the past 9 months. I have come to accept that this is my spirit animal
