Illuminate\Database\QueryException : SQLSTATE[HY000]: General error: 1470 String

Hi I'm getting this issue when I try to add this 'My name' for name field in user table. This is the complete error,

Illuminate\Database\QueryException : SQLSTATE[HY000]: General error: 1470 String 'a86d6173-6b17-43b4-992b-d414327bb4ff' is too long for user name (should be no longer than 32) (SQL: CREATE USER IF NOT EXISTS a86d6173-6b17-43b4-992b-d414327bb4ff@'127.0.0.1' IDENTIFIED BY '1d4fc2abfcb3987de68efb62122f496d')

I'm using laravel framework.

And this is a snapshot of my user table.
