dislocation: 2.	the act of disrupting an established order so it fails to continue. - dictionary.com

This pretty much sums up my definition of dislocation. Because we're trying to separate dislocation from disconnection and disembodiment, I think dislocation is specifically disrupting an established place. Something that messes with spatial relations is dislocation. Dislocation might be tied in with time; visually, it would be hard to tell if something in a picture was not supposed to be there in the first place. It would have to be a before and after series.

Example: A series of vacation photos of one person in different locations.


Disconnection

Disconnection is the complete lack of conceptual association between two things; two completely different ideas. Disconnection may also be tied in with what we expect and what we actually see. The separation between reality and our perceived reality.

Example: Lewis Caroll's Alice in Wonderland.

Disembodiment

Disembodiment is the lack of concrete form for abstract concepts. A shapeless idea. Disembodiment is probably the one out of the three terms that relies most on outside references. To be disembodied is to be simultaneously dislocated and disconnected.

Example: An inkstain on a desk.
