Laravel 5.0: Migration Refresh Error

I am an absolute beginner of laravel.

I would like to make some changes in my database. but when I try to refresh my databases, I keep dealing with the error below.

Before making this post, I googled so much and read many references. However, none of that worked and helped me solve the error.

Has anyone encountered this error before? Any advice would be appreciated. Thanks in advance.
