At home you start trying to remove the lid of the jar. It comes off sooner than you expected, and smoke pours out of the jar, filling the room.
The smoke solidifies, and to your fear and amazement clears to reveal a large dragon, taking up most of the free space in the room.
The dragon looks oriental, but instead of being streamlined, like chinese dragons you see on vases, it is fat and bulky and looks rather cramped in the room. The tip of it's tail is still inside the jar you hold.
The huge creature shifts, turns his head and stares down at you with peircing, glowing eyes.
