Dark Light Dwellers (UN-D-7983)
2. The well meaning but now defunct paranormal advisory department to the British Government (PADUK) issued a pamphlet to its senior ministers and armed forces on the Dark Light Dweller phenomena following the "Sellafield incident".

Among its many recommendations, it suggested how to observe one of these creatures.

"Avoid looking directly at the subject" it recommended instead that to observe them you should look aside and view them in your peripheral vision.

PADUK's advisory leaflet also recommended...

"to be aware of telltale signs of their presence, such as momentary interference of electrical equipment, TVs or computers, or a commonly heard buzzing of mobile telecommunication equipment".
