>Let's learn more about yourself, what are your goals? Who are you? What do you remember before you were here?

seconded, but try to get these answers by interviewing the life-size doll

What do you and the doll have in common? Well, you're both unusual grey humanoids. You have rounded, darker torsoes, or are those clothes? You have a pocket at least. Your legs are black and fibrous, and so are your arms when they arbitrarily appear.
The fact that the doll is inanimate, and that neither of you have mouths, makes it difficult to set up an interview. You'd have had better luck interviewing the tiny version of yourself inside the safe, but that's none of my business I guess.
The first thing you remember is standing in the corner of the room with the safe set at 000. It's harder to put a finger (if you had any such thing) on your goals. You recognize some objects, but you don't have a clear concept of any outside world. It's probably easiest to sum up your motives under curiosity, but the mysteries of the safe and the room (assuming the two aren't the same thing) aren't yet clear.
