Call Auth:user() Laravel in extend Controller

I create my controller:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class ResponsaveisController extends InternoController
{
}

I try to access Auth::user() multiple forms, all times return NULL

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Auth;

class InternoController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        var_dump(Auth::user());
    }
}

Would anyone have any suggestions on how to solve this issue?
