In 1979, Ruth Montgomery published Strangers Among Us, a collection of accounts of walk-ins. She included prominent historical figures among her subjects, such as Thomas Jefferson as having hosted walk-in spirits who wrote the Declaration of Independence.
Subsequently, a belief system grew up around the walk-in. It included attributes such as the concept of ascending into higher frequencies of evolution, a variety of psi powers, traditional “predictions regarding Earth Changes” first cited in the Bible (Book of Daniel and the Book of Revelation) but popularized by Edgar Cayce, and predictions of dire fates for those whose vibrational levels remain unraised.
In the late 1980s and early 1990s a channeling team known as “Savizar and Silarra” (Extraterrestrial Earth Mission), emphasized their walk-in status, claiming successive walk-in experiences together with corresponding name changes. The walk-in belief system now includes a number of variant experiences such as channeling, telepathic contact with extraterrestrial intelligences, or soul merging, where the original soul is said to remain present, coexisting or integrating with the new one. As of 2006, an increasing number of people claim some type of walk-in experience. Walk-ins were featured on the June 4, 1999 segment of the Unsolved Mysteries television series. According to information presented on this program, there are walk-in conventions, one of them drawing approximately 500 people.
