What does it mean when you dream of snails?

It depends on what a snail means to you. Being an individual, only you can properly assess what it means when you think of snails. Here are some of my thoughts though:

Maybe something is slow in your life

Maybe you want something to change or manifest in your life and you are impatient

Maybe someone made you feel small and insignificant

Maybe you are slowly beginning to understand a new conflict

You see, what else was also present in your dream and how you felt can also affect the meaning of the snail.

Best of luck.
