It's a fantasy role-playing game.

DM: You are Vex Vex'ahlia, a half-elf ranger . You are the member of the famous group of adventurers. Previously, The one in front of Grog quickly moves to his side and grasps onto his armor, pulling him in. It attempts to bite into the goliath, but its fangs catch and deflect off of the little bit of chainmail around his neck, given to him by Scanlan.
DM: Yeah, so the first one slashes across the side of your shoulder, but you manage to pull out of the way just in time to lessen the impact. This, however, sets you up for the easily dodged second blow. You swoop out of the way just barely in time, feeling the wind (whoosh) above your head. That ends their turn. Now we're at the top of the initiative order: surprise round. This would not have been enough noise to wake you guys yet, so you're going to hold on until somebody can get your attention. Top of the round will be Vex.
Player: I'm going to say Wake the fuck up! And I am going to-- can I hide? Is that what I do as my bonus?
DM: You have nowhere to hide in this room, unfortunately.
Player: Even if it's super-duper dark?
DM: You get the idea that these creatures probably aren't largely affected by the dark.
Player: That makes perfect sense. I'm going to Hunter's Mark the one that looks the strongest.
DM: Okay. The one that's most visible to you would probably be this one going after your brother. You mark that one.
Player: I am now going to attack him with my blazing bow.
DM: All righty, go for it.
