[SCP-966, Sleep Killer]

[Object Class: Euclid]

[Description: SCP-966 is a predatory creature that resembles a hairless, digitigrade human and possesses an elongated face with a mouth lined with needle-like teeth. On each hand, it has five claws that can be up to 20 cm long. Although sharp, these claws are easily broken, making them unfit for combat. SCP-966's height ranges from 1.4 to 1.6 meters, and it can weigh up to 30 kg. Physically, SCP-966 is weak, possessing hollow bones and low muscular density. It does not seem to rest through sleep; instead, it will suddenly cease all movement at seemingly random intervals, resuming normal activity three to five minutes later.

SCP-966 is visible only at wavelengths ranging from 700 nm to about 900 nm. This applies to all its tissues. If its skin, muscles, or organs have suffered from second to third-degree burns, the affected areas will be visible at wavelengths ranging from 360 to 900 nm.

SCP-966 feeds on medium-to-large-sized animals, including humans. It hunts either alone or in pairs. Its hunting methods consist of emitting a single burst of a previously unknown type of wave (dubbed ██████ waves, in honor of the late Doctor ██████), which permanently inhibits the ability of the affected creature to enter any of the NREM and REM sleep stages. The ability to micro-sleep is also lost. The effective range of the ██████ waves is up to 20 meters; however, tests show that they can be blocked by post-transition metals, particularly lead.

All attempts to make victims of SCP-966 sleep have failed. It is still possible to induce other forms of unconsciousness, although these will usually prove detrimental to the affected subject as they do not provide true rest.

After depriving its victims of sleep, SCP-966 will stalk its prey until a lack of rest incapacitates it. At this point, SCP-966 will proceed to consume it. SCP-966 has proven to be very agile and silent while stalking its victims. Occasionally, it will deliberately make threatening noises around its prey to further stress it and may even physically assault it if the victim proves to be particularly durable.

Other than the common symptoms caused by sleep deprivation, some victims of SCP-966 have shown signs of suffering from extremely vivid hallucinations, as well as sudden bouts of rage with no apparent external stimuli. It is currently thought that these are the effects of prolonged exposure to ██████ waves. Why SCP-966 continually exposes these waves to only some of its victims is unknown. One hypothesis is that SCP-966 will only do this when starving since it further degenerates the physical and mental state of its prey, incapacitating it at a faster rate.
