Description: SCP-699 is an ancient door, measuring approximately 2m x 1m, made of dark brown wood, with intricate patterns carved on its surface. The door has no hinges or handles, but it can be opened by pressing on a specific area of the surface.

Phenomenon: When an individual steps through SCP-699, they are transported to a future version of themselves, in a world where all events and phenomena are influenced by the decisions they have made in the past. These individuals have the opportunity to witness the outcomes of their actions, ranging from positive experiences to severe consequences.

However, returning from SCP-699 is not always easy. Some individuals have become trapped in the future world, unable to find their way back or due to the shocking experiences they have faced in the future.

Containment Procedures: SCP-699 is contained in a special holding cell at the SCP facility, with strict security measures in place to prevent anyone from accessing the door. Experiments are conducted under close supervision, aiming to study the impact of SCP-699 on the psychology and behavior of individuals upon their return.

Additional Notes: Some individuals who have returned from SCP-699 have reported changes in their personalities, as well as difficulties in accepting the present after witnessing the future. This has raised significant concerns about the psychological effects of SCP-699 on its users.
