From the story I don't think they are just looking at areas of the brain that show activity. They are actually intercepting the signals from the retina to the brain and translating it. This is pretty major. This isn't simple MRI images.

  But if you're dreaming, are your retinas registering anything? I wouldn't think that the brains visual centers are processing in the retina, but in the visual centers and it doesn't make physiological sense to send those images 'back' to the retinas.

    REM (Rapid eye movement). It is believed that people actually "see" their dreams.
