Here is the meaning I found:
To see a turtle in your dream symbolizes wisdom, faithfulness, longevity, and loyalty. It also suggests that you need to take it slow in some situation or relationship in your life. With time and patience, you will make steady progress. Alternatively, a turtle indicates that you are sheltering yourself from the realities of life. You are putting forth a hard exterior and not letting others in. As a result, you are feeling withdrawn.To dream that you are being chased by a turtle indicates that you are hiding behind a facade, instead of confronting the things that are bothering you.
To see a tortoise in your dream symbolizes perseverance, determination, and longevity. You need to take some chances in order to get ahead in life. The opportunities for advancement are opened to you, but you need to take the next step. Alternatively, the tortoise represents the need to be sheltered or protected from life's problems.
