Oh, my bad, it isn't Disney land, but Disney ride. (not that much difference) And it's from the book. I'll copy the part for you where it is mentioned:

Here I need to put in a word or twenty on the nature of reality, and of these alternate worlds. A guided meditation, as we’ll go into in the next chapter, is not the same as journeying. That doesn’t mean that when people do a guided meditation together, they aren’t going anywhere but their own heads. They might be going somewhere in their own heads, or they might be visiting a a kind of archetypal world-space that seems to exist as a cosmic construct attached to the collective unconscious. This cosmic construct, like a Star Trek holodeck, is sensitive to those who touch it, and can become a kind of idealized facsimile of wherever it is that they are trying to go, be it Asgard or Brooklyn. Most people who go there realize suddenly that they’re somewhere besides their own heads—wow!—and decide that they are really, truly in Asgard or Olympus or wherever it was that they were trying to go. This can happen with early attempts at journeying, too. In fact, some people never get beyond this place.
The problem is that it’s not really Asgard or Olympus or even Brooklyn. Going there is rather like going to Disney’s Epcot Center World Showcase and then saying that you’ve been to China, Italy, and Mexico. In fact, those of us who worldwalk regularly refer to it as “the Disney ride”. In a Disney ride, everyone speaks your language, is friendly and helpful, wants to make sure that you have a good time, and never tries to kill you. If you throw popcorn at the waving god puppets, the worst that will happen is that you might get bounced out.

...

Many books on shamanism stress that world-walking is entirely safe, or mostly safe as long as you don’t go into those nasty areas, which will of course be clearly marked in a way that a modern Westerner will find symbolically meaningful. When I read or hear this, I have to assume that they’re all on the Disney ride. Not that there’s anything wrong with that; the Disney ride is put there for a reason. I’d rather have ugly Americans being ignorant and obnoxious at the China World Showcase than in Beijing, and I’d rather have seekers trying to enrich their lives and learn more about themselves during guided meditation to the “archetypal spiritual holodeck”, as a friend put it, than actually bothering real nonhuman individuals on their own territory.

Oh its a terminology of his own that he used in the book to describe the astral realm itself LOl..see how English can be read totally the wrong way.funny..

Yeah, it is funny. I like that the real exploring of spiritual realms is still existing and well among some groups.
