Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: No personnel is allowed to be tired when in the area of the entity, guards must be checked every hour to keep them from sleeping near the entity. If a guard is found to be tired they are to be replaced immediately due to the effect of SCP-XXXX. The entity has little power in the real world but in dreams it is depicted as a demon. The dreams with the entity in it starts out in a white building (the building is different in every test). With the person is with their family (family is unable to be suffocated unless in the vicinity of SCP-XXXX). The dream becomes dark for only the subject. While the dream is dark the subject starts hearing the phrase "The Darkness Suffocates" while having a crushing feeling then the feeling goes away after the phrase is said. The Darkness causes people to suffocate in their dreams and they suffocate in the real world. It is unknown how the entity suffocates people in their sleep. No one is to be allowed in the containment area of SCP-XXXX as it will [Data Expunged] while people are in the containment area of SCP-XXXX. SCP-XXXX is contained at Area-02 in an airtight containment unit. SCP-XXXX-1 can get through any air filtration unit however it must leave SCP-XXXX-2 behind because SCP-XXXX-2 is just floating inside of SCP-XXXX-1 and isn't a part of SCP-XXXX-1. If SCP-XXXX-1 leaves containment its [Data Redacted] effect still happens but the people who are asleep near SCP-XXXX-1 will not suffocate. Gas masks keep SCP-XXXX-1's effect from happening on those in the containment area

Description: SCP-XXXX is a cloud of darkness known as SCP-XXXX-1 and contains a dark colored humanoid creature inside it known as SCP-XXXX-2. It is unknown if SCP-XXXX-2 can speak as it has never been observed moving. SCP-XXXX-2 can't be viewed on cameras due to an effect of SCP-XXXX-1 which blocks cameras from viewing inside it. SCP-XXXX-1 appears to be a black cloud made of the same thing as a normal cloud but with black ash mixed into the cloud and the cloud is quite toxic. SCP-XXXX-2 is a black humanoid creature that doesn't move unless someone is sleeping in the area of SCP-XXXX-2 then SCP-XXXX-2 appears to be the one who suffocates the sleeping person. SCP-XXXX-2 appears to be 1.75 meters tall and weighs about 70 kilograms, SCP-XXXX-1 width and height ranges from 3 x 5 meters to 15 x 25 meters.

Anyone found in the containment area is to be removed immediately by 4 level 3 personnel while wearing gas masks. Once the subject is removed from containment the subject is to be interrogated then given class A amnesics.
