La La Land

Someone who is out of touch with reality as in being in their own world.

Someone unaware of their surroundings, either due to lack of intelligence or simply because they are sleeping.

Examples of people like this are, Forest Gump, Kimchee, Weish on night and day shift, and so on.
People also tend to go to La La Land in Macs basement, so be careful of your surroundings.

DAMA was not aware of what La La Land was because he himself was in La La Land.
