The best way to learn RV is to be taught in person by someone who knows themself.Everyone can do it,there are no boundries.
I stumbled across this subject in the early 90's when I read Moorhouses book by chance.Never heard of it before in fine detail and the book hooked
me.I have also read browns and moneagles(sp)books and looked into swann.Recently Monroes out of body books have hit the mark too
You realy need a teacher,and in person to show you how to do it.It would be too easy to read a bit online and try it yourself and just imagine
things.It takes time to get the framework memorised and the grid of the matrix probed with your subconscious rather than with your awake state
Its also no where near as glorious as mentioned in the books you may have-or the films you have seen.If any thing you see things as quick low res
photos as your subconscious guides your pen(crv)It can get very confusing.During one target I described a target as a park in the city,once that lock
is achieved your mind then throws out normal awake stuff related to what the mind percieves as a city park woud have
-then all of a sudden i write down (sharp long blade) as the subconscious guides me before my rational mind takes over.It just takes practise to get
used to using your mind this way and eventualy you will know when your subconscious is leading you or when your mind is doing its own fairy tales

The city target above was when a young mother was murdered in the park a few years ago.My instructor was trying to get me to (without leading info) to
name the killer but I couldnt get any further than the blade and I wanted a break too.
So find someone local who will be willing to teach you,it might not come cheap but thats life.Also get used to the many WRONG targets you will do-Its
a nasty learning curve you have to go through to get results that work.
I failed with monroes death(my mind went all crop circles)
Jesus on the cross(my mind decided it was car speed desert tests)
Mars-(anything with et related I missed by a long shot)
I have had a few good ones-TWA800 was seen as a still image that lasted for about 6 seconds of the plane infront with an orange glow behind it and
naval exercises nearby
JFK was a long image of a bullet and I drew a picture of a house with two straight lines coming out of it-my awake state decided then to add another
and make it look like a triangle
Plenty of other targets too,but its been a long time and i have moved on
Does it work?is it realy your subconscious or your imagination?The only way to find out is to do it yourself.Hopefully you wont get headaches like i
did.good luck
