Almost sounds like a fast heart beat.
I am sure you could probably find a reasonable explanation like power surges or a short...I knw sometimes power lines can pick up weird signals and
pass them into your electronics in the house, almost like radio interference. However, I don't like those explanations....what YOU feel it means when
it happens is why it is happening.
I know first hand that spirits can and do effect electronic equipment like radios, police scanners, computers (although it seems not so much with the
newer ones, my old 486 was definitely haunted)
I think it is what it is.
