There are different ways of experiencing non-physical realms. The most difficult being in the way of a full-blown "out of body" style experience. The reason is because it takes an exceptionally high degree of mental control which generally takes a *lot* of practice to attain.
I always say that it's one thing talking about entering the Astral by flying through some entrance-structure (such as the one depicted on the back cover of Astral Dynamics) but it's quite another thing to actually do it!
The Focussed Attention methods of Bruce Moen rely on a series of concepts which are much "kinder" to the individual. With the traditional route, it's a full-on, right-in-your-face experience that's there is no getting away from (except for being zapped back to Physical). The Moen-route is a step back from this. Rather than experiencing situations directly, they are taught to build-up a mental picture from using a number of non-physical "tools".
The immediate advantage is that the moment anything starts to go awry, an individual is able to take a step back from the experience and hold it at arms length, so to speak. They are then taught to call on an "interpreter" to act as a kind of go-between. An interpreter's job is to offer advice on how best to proceed, or explain the nature of the circumstance, and so forth. Which is all very much easier on the senses.

Out of body and focused awareness are very different to some people.

As you can see, the well-respected Bruce Moen says you can goto F-27 aka, the spirit world, about as much as you want with focused awareness, whereas with obe, if you've read Astraldynamics, you'll notice Robert Bruce has only been there about 4 "precious" times using the Obe method.
I've also heard many accounts where several people that use hemi-sync have been able to go even farther than that.
