What's the Worst that Could Happen?

Maybe you need to put your hand on the scanner to start the exhibit? It's just a haunted house exhibit, it's not going to launch a nuclear missile or something crazy. You put your hand on the scanner and see a white-blue light run across your hand. Then suddenly you feel a tiny prick on your index finger and pull away. You look at your finger and notice the barest hint of blood.

"PROMISING SUSPECT DETECTED. COMMENCING DETAINMENT PROCEDURE." A harsh mechanical voice issues from the device. The glass tube rises revealing even more machinery within, and suddenly a pair of mechanical appendages with pincers on the end grab your arms and drag you into the chamber. Before you can try to leave the tube drops back into place, and the machinery unfolds and begins to emit more white-blue light, washing over every inch of your body.

"PRIME CANDIDATE CONFIRMED. COMMENCING CONVERSION." The voice states again, though it sounds muffled in the tube. A gas vents into the tube from the top, and a blue liquid begins to bubble up from below. The machinery begins to restrain you, and you yelp in pain as something is injected into you from various points. The machinery near your head forms a sphere and then collapses to cover your head and you feel even larger objects embed themselves into your spine and neck.

Suddenly information floods your mind. You can't even begin to parse it all, but it continues to come and then you gradually come to be able to understand it more. You can see the origins of the machine you were in - a mad genius creating a device to manifest the supernatural and dying before it can be properly used. Then a mistreated apprentice works on his own project, trying to use his teacher's device to bring his own dream of a machine to bring about a golden age to fruition, only to die in an accident. Then your mind flies through time as the house is abandoned and stands empty for years, passing hands until your brother comes into possession. You see an employee managing to carelessly active the original device without even realizing, and the occult energy flows through the house and reaches the room you are within now. A strange machine is warped and expands, eventually converting the room to it's current state. You feel a cold intelligence awaken within, disgusted by the flaws of humanity in spite of it's charge to save it. You feel it rage as it realizes it cannot escape the house due to the nature of the supernatural means of it's creation, and then a return to calm as it schemes to enact it's plan.

The machine learned that other inhabitants of the house could spread their influence via the conversion of those from outside. It dedicate all it's resources to the ability to take a single human and turn them into a vessel through which it could enact its' mission. Your body knows synthetic perfection, but now your mind must be molded as well. You realize with horror as even more information floods your mind that the machine is trying to turn you into a mental copy of itself, and you desperately try to maintain your sense of self.

Suddenly you become dimly aware of the tube opening as the machinery pulls away from you and the liquid spills out into the room. Consciousness comes to you.
