not quite nightmares...

....but being plagued by bad dreams. The kind that leave you shaking and have your heart racing, where you wake up nearly crying and can't shake the feeling for hours. Only a few details stay into consciousness, just enough that you know you had a rough night and that the "rest" wasn't truly restful, but not enough is left to allow you to examine and dissect the dream and dismiss it or understand the roots of it. So you wander through the day, disconnected from reality by a weird hazy buffer of remembered emotions and not enough rest, hoping you are faking it well enough that no one asks.

Ensign, divert all available energy to emotional shields...engage mask on my mark.

Engage.
