Dreamrealm

The Dreamrealm (also spelled as the Dream Realm) is a mysterious realm only existing within the deep subconscious of Earthrealmers and perhaps others, and is where the wraith Freddy Krueger resides.

It reappears in Tremor's ending in Mortal Kombat X. Kano had sent him and other Black Dragon members there to retrieve a psych-bomb; exposure to the realm's ethereal power increases his strength and expands his mind, transforming him into a powerful demi-god.
