Sleep-Transferring Pillows

Origin
The origin of these artifacts are unknown.

These artifacts were responsible for the death of a married couple after having recently moved into a new home with these pillows.

Over the course of several weeks, the husband complained of increasingly frequent and long sleepless nights while his wife slept in more and more. Eventually, the husband was unable to sleep entirely despite all attempts at relaxation and medication, culminating in heart failure from his body's lack of rest; his wife, meanwhile, was finding it harder and harder to wake up and stay awake despite multiple loud alarms and increasing intake of caffeine, culminating in a permanent coma followed by brain death.

Claudia Donovan collected this artifact early into her field career.

Effects
When both pillows are used, the ability to and duration of one pillow user's sleep is transferred to the other, resulting in decreasing sleep for one and increasing sleep for the other. If allowed to continue, one user will be unable to fall asleep entirely while the other will fall asleep as soon as they make contact with the pillow, and will sleep deeper and for longer over time.

This will eventually culminate in heart failure for the sleepless user, as their body has been unable to rest for long periods of time and can no longer handle the constant stress. The sleeping user, conversely, will fall into a permanent coma they were incapable of being awoken from until their brains shut down enturely.

Trivia

 * This artifact was inspired by its creator, Garr9988, suddenly experiencing several sleepless nights for nearly an entire week with no known cause.
