Supplemental Record
The Envelope
During a routine Health records audit, an administrator noticed sealed envelopes filed behind several personnel medical records. Each envelope was dated, signed by Mira Yoon, and marked with the name of the employee whose file contained it.
The envelopes were not listed as official medical documents and contained no classification markings. When asked about them, Yoon stated that they were predictions.
One of the employees named on an envelope had recently reported persistent shoulder pain. Yoon instructed the administrator to open it.
The note inside had been written eighteen months earlier.
It described the same shoulder, the likely location of the pain, and the behavior Yoon believed would eventually cause it: incomplete rehabilitation after an earlier injury, poor lifting technique, and the employee’s habit of returning to full duty as soon as symptoms became tolerable.
The employee had been warned about all three at the time. He had ignored her.
A review found additional sealed envelopes in other files. Their contents ranged from likely repetitive-strain injuries and sleep-related problems to expected complications from habits personnel had repeatedly been advised to change.
Not every prediction proved correct. Several envelopes were eventually opened after years with no corresponding condition and contained forecasts that had simply never occurred.
When asked why she wrote the predictions down instead of leaving them as ordinary medical recommendations, Yoon explained that personnel frequently remembered warnings differently once the predicted problem actually developed.
Yoon: “People become very certain that nobody warned them.”
She stated that sealing the prediction prevented her from quietly revising it later to make herself appear correct.
Yoon continues to maintain the envelopes. Personnel are generally not told whether their medical file contains one.
Personnel Observation
Controlled Sleep
Yoon possesses an extraordinary degree of conscious control over sleep.
Before sleeping, she can determine either the exact amount of time she intends to remain asleep or a specific time at which she intends to wake.
Once she has made that decision and closes her eyes with the intention of sleeping, loss of consciousness generally occurs within several seconds.
Her accuracy is exceptional.
Controlled observations have recorded Yoon waking within seconds of a predetermined time after sleep periods ranging from brief naps to a full night's rest, without alarms, environmental cues, or another person waking her.
The ability does not appear to be something she consciously activates in place of ordinary sleep.
This is simply how Yoon sleeps.
Whenever she falls asleep, she appears to establish a wake time beforehand, whether deliberately considered at length or decided almost automatically.
The unusual control comes with a significant disadvantage.
Once asleep, Yoon is exceptionally difficult to wake before the time she selected.
Normal speech, alarms, shaking, changes in lighting, and other stimuli sufficient to wake an ordinary sleeper frequently produce no meaningful response. Considerably stronger stimulation can wake her prematurely, particularly pain, severe physical disturbance, or an environment her body interprets as immediately dangerous.
When prematurely awakened in this manner, Yoon experiences the usual disorientation associated with abruptly interrupted sleep.
She also reports some influence over the contents of her dreams.
Yoon does not claim complete lucid control. Instead, she describes being able to establish broad parameters before sleeping: a location, person, subject, activity, or emotional tone she would prefer the dream to contain.
The resulting dream may deviate substantially from what she intended, but according to Yoon, the selected subject appears far more often than chance would suggest.
Neurological examinations have identified no mechanism sufficient to explain either ability.
