I think it is spiritual big time self-deception,some of these people practice meditation & go into a mild suggestive hypnotic trance & think their vivid daydreaming are actual spiritual trips. When people are looking for spiritual experiences the deceiving spirits will take advantage & interact with unprotected gullible people and string them along, it is no different then what the psychics call their guides.
Although I don't buy they've been on any type of "spiritual journey," not even one akin to
The Pilgrim's Progress, if you catch my drift, it needs to be examined biblically. Well, perhaps they are one of the characters in The Pilgrim's Progress. I'd suggest a read of
Bunyan Characters to all.
So we must ask, are their teachings true? Is their Gospel understanding true? What does the Scripture then show us concerning those who fail in sound doctrine?
Is it possible that since some of those who reject correction and the word used properly that they would be allowed, providentially, to be deceived by a "spiritual journey?"
Yes, that is possible.
It is also highly possible they've convinced themselves of what they know is not true, which is a severe judgment of self-deception.
Even though being deceived by some "spiritual journey" is possible, I highly doubt any of their myths and fables are true as this seems to be the lot of those who won't endure sound teaching; 2 Timothy 4:1-4, as they prefer myths and fables to the truth and to sound doctrine.
These gather around others who also won't endure sound doctrine, and those who go beyond what is written; 2 Corinthians 4:6 while encouraging one another in their deceptions, and mocking those who hold fast to sound teaching; 2 Timothy 1:13.
The word of God on this site, has been delivered an attempted major blow by some (just look at some of the threads, and those who mock and mitigate Scripture while exalting their own "spirituality" as evidence). But it is of none effect to those who stand firm on the word. Keep standing brother, and brethren! :)
