So David Icke Is A Nutter?? What Icke Said in 1991, What One Of The World's Top Physicists Said in 2008 - David Icke Website
Although I don't understand or agree with everything on the video but frequency can be one explanation for Christ being able to walk through the door, St. Thomas being able to feel his hand wounds, the Blessed Mother standing on the Oak Tree at Fatima and people not being able to see her but being able to see the branches bend. The vision of hell showed to the 3 children being opened in the earth, "it was as if the earth opened" yet at the same time if humans in this dimension/frequency were to dig you would find just dirt and rock.
In these supernatural occurences there is something about being able to interact with this dimension while actually not being a part of it. Yet still being able to manifest things to people who still live in it.
