There are four volcanic plugs aligned with this road which may cause this optical illusion. Notice especially the length of the road where this occurs is 300 yards, very close to the width of the volcanic plug of Edinburgh Castle at 306 yards.
Using my divining rod I discovered that down the length of this road there is a form of ley line which is composed of individual waves of energy. The wavelength is noticeably reduced (more powerful) where the effect is noticeable.
Oddly, the wavelength in the fields on either side is not affected — it is only on the road itself where the amplified energy can be found, and I have read that the effect was not noticeable before the road was metalled.
Not every person can see this – some people don’t notice the illusion.
There are a number of “gravity” or “magnetic roads” around the world. For a list, click here.
