Dream of a Door and Sand

The dream seemed all too real, almost like a repressed memory more than a dream but you are sure down to the core of your being that it never happened.
 
In the dream you found yourself in a precarious situation. You had been tracking a lead on Kidra that led you to an old and abandoned temple. Cautiously entering it a huge, hazy door suddenly loomed in front of you that seemed to be a black as midnight and bright as the sun at the same time. It was locked and no matter which way you turned it stood blocking you. You knew that your lock picking skills were the only way to get pass it. 
 
As you knelt before the door, picking the lock with your nimble fingers, a strange sound filled your ears. It was a soft whisper, like the rustling of sand. Looking around you find find that the temple walls were now black, and a black sand was slowly pouring in from every nook and cranny. The sand was cold as ice, and it sent shivers down your spine.
 
Your heart raced as you realized that the sand was rapidly filling up the room, leaving you no time to pick the lock. You try to hurry up, but your fingers fumbled over the mechanism and lock’s tumblers refuse to budge.
 
The sand rises higher and higher and you feel the icy sand creeping up your legs, past your waist, and soon enough, it would engulf you completely. Before the black sand steals away your sight out of the corner of your eye you notice a figure, silhouetted against the black walls of the temple. All you can remember of this dream figure is he or she is wearing a fine coat and has a monstrous face of white fur and several thick horns. He, she, it seems to be watching you as you drown in the black sand, observing your every move.
