SCP-990 is generally a human male dressed in a Cold War era business suit who appears to Foundation personnel through dreams. Thus far no Foundation personnel have encountered SCP-990 in the real world; if he corresponds to an actual human being, we have yet to find him. Presently there have been no reports of SCP-990 appearing to non-Foundation personnel.
SCP-990 does not appear in-game. However, upon loading the game, if the player encounters the "CWM" loading screen, audio clips of SCP-990 will play. These audio clips will contain quotes of SCP-990 talking to the player as if they were in a dream.
The audio clips for SCP-990 were done by TheVolgun.
Before v0.7.2, a mysterious figure would occasionally appear in the background of the loading screen. The figure was often speculated to be either SCP-990 or a member of "Nobody".
The audio files for SCP-990 in the game's files have the extension .cwm. These files can be converted to .ogg by changing the file extension if one wishes to listen to them outside the game.
SCP-990 is primarily considered Keter not because he can harm, but instead because he poses a serious risk about the releasing of information about the Foundation and so risking to break its anonymity. It is also unclear as to whether he causes incidents to happen or merely predicts them.
SCP-990's nickname "The Dream Man" May be a possible nod to G-Man from the Half Life series. Under inspection, both wear suits, both have eerie voices about "Waking Up" and both appear in their late 40's.
In the early versions of the game, if the player remains idle at the pause screen for too long, the screen would unpause and SCP-990 can be heard saying "Stop Hiding..." however this can still happen when opening the pause screen
When put through SCP-914 on coarse or rough and put an item it will get destroyed (not all the items),in 1:1 it will give you something similar to the item you put in SCP-914, then on Fine or Very Fine it will turn items to "Fine" items.
Appears to be a stuffed bear shaped from what is believed to be human ears. May be found in some hallways and screams at the player if approached. The scream causes ears to grow all over the player and in the lungs which results in death after a few seconds.
