What does it mean to see yourself playing with a wolf in your dream?

It depends on the mood of the dream.

If it is truly a playful dream, it may mean that you are doing something dangerous and should be careful, but aren't afraid.

If you had the feeling in your dream of danger, then you might have been in a situation with something or someone you knew was dangerous but had no choice but to be around them.

Or,

you may have just watched something with wolves on TV ,had a conversation about them, or read something about them.
