>>5863776As you approach the door you can hear a low hum coming from behind it like a powerful ventilation system, and what sounds to be faint voices. You are unsure of if to call out, as you can't even be sure if the warbled sounds are voices at all. As you inspect the door, there appears to be no doorknob on your side, however the hinges are visible, meaning that the door opens inward on your side.
