Ghosts of the A23, The London Road to Brighton.

For a long time now there have been reported figures, on the A23 Road to Brighton. One is a Ghost of a Young Girl who crosses the A23 at the Village of Pyecombe at a Crossroads, just before what was a Texaco Petrol Garage. I have not personally witnessed it, but there has not been any eyewitness encounters for some time. In 2007, I was travelling by Bus, as the line was up between, London and Brighton, and I was visiting a friend in Brighton to do some shopping. I had a great day out and climbed the bus in October, for the return journey, which was bumpy and uncomfortable, although more picturesque, then by Train.
We had left Brighton, I had settled down on the Top Deck of the Double Decker. I looked out as we joined the A23 Brighton to London Motorway and I sat down towards the back end. It was dark and the entire Motorway was lit up by Neon Amber Lights. The rain had come down in puddles and the Windows of the Bus were steaming up on the outside, from the Hours of Dead Straight Rain. I put on my MP3 Player and listened to the ABBA Gold Album, I had received as a Birthday present, and I turned up the volume for ‘Momma Mia’.
We were just beyond, ‘The Chesnuts Riding School,’ when suddenly I heard very loudly in my Right and Left Ears, which drowned out the Noise from the MP3 Player Children’s Voices, of a Girl and Boy, which was laughter and Joking, and it sounded as if they were involved in a Game. It lasted two or three minutes, and then was gone. I looked around to see if someone on the Bus was causing it, and there was no one. The only other individual on the Bus was seated at the Front , and he was listening to his MP3 Player.
I did not think more about it until I returned home and casually spoke to my farther, he suggested that it was a stray Radio Signal that entered my Brain, in which I processed and heard. I do not really believe him, and feel that the explanation remains a Supernatural one. It was definitely Children’s laughter and voices, and that certainly would not have been broadcast by a Radio Station. The A23 is set in a Cut through the Downs, and The Downs would act as a filter blocking out radio Signals. I don't believe it possible for Radio Signals to penetrate and go through the Skull, and again How could I translate it as sound ? I believe that the voices belonged to one of the many figures that often Cross the A23.
