It's a fantasy role-playing game.

DM: You are Vax Vax'ildan, a half-elf rogue . You are the member of the famous group of adventurers. Previously, They learn that the corpse was killed by a woman who was not supposed to be there, some 14 weeks ago. The corpse has since seen others pass by, particularly a dwarf.
DM: Okay. You (sniffs) and it clears your sinuses up pretty well. Much like a fresh dab of wasabi, your nostrils are a little more open. Because it's not sulfurous, it doesn't have something similar to what you'd find in smithing in your experience, at the very least. It's hard to really place where it comes from. You said you're going which way?
Player: Towards that other door that they did not come out of.
DM: This here? All right.
Player: 23 I rolled, perception.
DM: 23. You approach the door. This door is locked. It does not appear to be trapped.
Player: Okay. Let's unlock it.
DM: Okay.
Player: That is a 21.
DM: Okay. As you reach down to the lock and you place the picks inside, start fiddling, you look at the iron around it, and the actual metal seems to be frosting over. You pull back your head, and as you exhale, your breath becomes visible and the temperature seems to drop significantly, and as soon as you look up at the wood, something shimmers in the wood, and it's a humanoid face that just pushes out of the wood.
Player: Can I use Uncanny Dodge to roll backward right now?
DM: Right now?
