It's essentially Alucard in disguise. The Revelations DLC has revealed that Alucard can Asral project the four-legged white wolf, which as shown in game he can use to sneak past enemies. When you see the white wolf during the main game, the wolf is visible to Dracula but also has that same aura mist that YT has. Basically, YT is ALucard projecting the image of himself as a kid in order to get Dracula to remember the man he was.
