Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: A 10 kilometre perimeter has been established around remote base XX, which is located directly above SCP-XXXX-1 Entrance and exit from base XX is solely permitted to individuals who have received level 3 or higher clearance. Express permission from individuals with Level 4 or higher clearance and detailed knowledge of SCP-XXXX is required for use of the deep chamber and perform explorations around and into SCP-XXXX-2.
UPDATE NOTICE: As of ██/██/████, exploration into SCP-XXXX-2 is forbidden.
Description: SCP-XXXX is the collective designation for two distinct entities, hereafter individually labelled SCP-XXXX-1 and -2.
SCP-XXXX-1 is a circular underground tower located near ████,███. SCP-XXXX-1 is constructed out of black limestone in a Romanesque architectural style, with large floors every ██ metres, connected by descending spiral passageways. The outer perimeter of the floors and passageways are lined with Doric order columns that extend from the floor to the ceiling.
It is currently only possible to enter SCP-XXXX-1 via SCP-XXXX-2, as any other attempts to reach it, such as via digging, results in the area where SCP-XXXX-1 would reside instead having ordinary rock. There is however, no known way to exit SCP-XXXX-1. Any all and all attempts to dig from within SCP-XXXX-1 into the encasing rock beyond the perimeter of tower have all been met with failure.
SCP-XXXX-2 is circular tower located within a highly lucid, anomalous dream that occurs if an individual enters REM sleep while inside or within ██ meters of SCP-XXXX-1. Affected individuals, hereafter referenced as SCP-XXXX-A, are fully aware that they are dreaming, and are able to wholly control their actions. In addition, they are able to stream video and audio information to people outside the dream if they have the means to (such as via a camera or radio). Time passes within the dream at a rate identical to real time, and the dream always remains constant, despite SCP-XXXX-A instances exhibiting a standard sleep cycle. SCP-XXXX-A instances will awaken after █-██ hours, with no recollection of the events that occurred while asleep. Instances can be awoken prematurely via external stimulus, such as events that would ordinarily wake up someone from sleep, but they are unable to do so by themselves.
The dream SCP-XXXX-A instances experience is always the same, unless they are inside SCP-XXXX-1. Instances will find themselves in a grassy field with SCP-XXXX-2 located in the centre, which is identical to SCP-XXXX-1, except that it is constructed out of white marble, and is located above ground.
If an SCP-XXXX-A instance awakens while inside SCP-XXXX-2, their body, and the current clothing/objects they are wearing/holding, will immediately disappear and reappear within SCP-XXXX-1. From this point onwards, SCP-XXXX-A instances will alternate between existing within SCP-XXXX-1 and -2, depending on whether they are currently awake or asleep, with no recollection of what has previously occurred in one while in the other.
