Redirect to current page:

if ( $this->request->is( 'post' ) ) {
    if ( $this->Auth->login() ) {
       $this->redirect($this->Auth->redirectUrl());
   } else {
      $this->Flash->error(__('Your username or password is incorrect.'));
   }
 }

If you're trying to redirect to a specific place on login, make sure you've set loginRedirect when you initialize the Auth Component in Appcontroller.

public function initialize()
{
    parent::initialize();

    $this->loadComponent('Flash');
    $this->loadComponent('Auth', [
        'authenticate' => [
            'Form' => [
                'fields' => [
                    'username' => 'email',
                    'password' => 'password'
                ]
            ]
        ],
        'loginAction' => [
            'controller' => 'Users',
            'action' => 'login',
            'prefix' => false
        ],
        'unauthorizedRedirect' => $this->referer(),
         /* You need this part */
        'loginRedirect' => [
            'controller' => 'dashboard',
            'action' => 'index'
         ]
    ]);

}
