Doppelgänger (2022)

Thomas is at home, alone and tipsy, talking with his over protective mother at the phone. He has a sudden migraine when he sees his reflection behaving differently than he does. At first he think he had one too many drinks, but things becomes very real when a hand comes out of the mirror and drags him in. In the mirror Thomas finds his Doppelgänger, who traps him there and steals his place in the real world.
