SCP 3966 Falling Out

Sleeping is something a typical human does every single day, usually for hours at a time.

Despite this, sleeping and dreaming is still a field of science that is constantly being researched,

discovering how our body and mind

works while sleeping, new ways to help people fall asleep or get more restful sleep, and the

specific science behind dreams.

There are a good number of SCP articles related to sleep, ranging from fanciful to simply

odd, but SCP 3966 falls firmly in the unsettling category.

SCP 3966 is a neuroactive polypeptide found in humans that contains no sea terminus.

If you don't understand what that means, as I don't,

all you really need to know is that it's an anomalous chemical found in some humans,

which brought it to the foundation's attention.

It is found in the cerebro-spinal fluid of a high percentage of people that died while sleeping, although not every person, it seems. When discovering an anomalous chemical in dead people, the foundation first decides

to try injecting some of it into the spine of a living D-class. 11.5 seconds into the process,

the D-class undergoes a sudden withdrawal reflex as their body tries to react to the injection.

They are restrained, but there are no further responses, and after 30 seconds, the researchers

withdraw an equal amount of fluid from the subject to balance things out.

The D class reported a sudden falling feeling after being injected,

and an EEG reported numbers consistent with stage 1 NREM sleep

a second and a half before the D-Class had reacted to the injection.

These responses are consistent with a

hypnic jerk, an involuntary response when someone is falling asleep and suddenly jerks awake again.
