An excerpt from Visionary Articles from Rosemary Ellen Guiley

We already have evidence of spontaneous occurrences of tunneling. Besides teleportation, tunneling may explain some (but not necessarily all) mysterious disappearances, invisibility, UFO abductions, Men in Black, fairy abductions, Bermuda Triangle disappearances, mediumistic apports (objects materialized by mediums), Bigfoot, Mothman, and a wide range of Fortean phenomena such as sudden appearances of strange creatures, rainfalls of frogs and other oddities.

In the November 2001 issue of FATE, author Scott Corrales writes about “Nonpeople From Nowhere,” in which odd people claiming to be from unknown places suddenly appeared somewhere, and just as mysteriously disappeared. And, entire lands, like the Hesperides Islands, have seemed to exist and not exist.

These cases have been documented throughout history and around the world. I think spontaneous tunneling may be the cause.

Tunneling may also account for some ghost experiences. Some ghosts may be remnants or recordings impressed in psychic space, but others may involve living people. Perhaps someone in another place in time doesn’t come through entirely, and so we see an apparition instead of something solid.

This article doesn’t talk about the traditional sci-fi method of time travel, but time travel through our higher consciousness. Fascinating stuff.
