I used to have the teeth dreams too. They'd all come loose one by one and I could just pick them out.
I also frequently have had dreams about being chased by bulls and having to scale a wall to escape them.
Any amateur psychologists out there??
Whether it be a bull or tiger or lion represents whatever fear you have, hence you being chased and getting away. Which means your one step ahead of your fears.
I think I'm in the right ballpark with these answers. Or I could be full of bullsh!t. Make what you want out of it. Because their your dreams not mine.
