On the phone, an acquaintance of yours sounds panicked
I know it sounds crazy, but you gotta listen to me.
Earlier today I got assaulted by a group of robed people, and now I just woke up in the middle of what looks like a hallway, and I'm stuck there! I see doors left and right and I think "Oh, well, no harm in listening". And you wouldn't believe what I heard!
"I would like to solve the puzzle", is what I could hear on the other side of that door, and the next door in line just had grunts and cries of what seemed like pain. So I kept going, and the third door I saw was silent, so I opened it. And inside was a corpse! A man hung from the ceiling! What am I supposed to do when I see that?
You have to help me dude, I want to get out of here, I just want to get back to the real world. Opening more doors sounds risky, and I know you're super smart, so please help!
You take a bit of time to think, which door should your friend open?
