In work at my desk, listening via headset to a recording of a presentation by a colleague.
The same colleague walks over to my area and talks loudly to another colleague, so I am hearing his voice in person and though the headset.
This seemed to completely discombobulate and confuse my sensory systems and I found myself incapable of tracking either conversation.
It was like my system was saying "this should not be happening."
Anyone else have similar experiences?
