It's technology. If someone/something can read your mind they are either reading facial cues or you have a brain implant.

The facial cues in reading what a person is thinking is underrated a bit. If you have a knack for it you can get a gist of their underlying emotion, movement of the eyes for type of thinking pattern (jutting eye motion means dismissive of idea in their mind - something they disagree with). Often autism is looking at for having a disorder of not being able to read facial cues; however, not much is researched into people who can read facial cues much better than average.
