Can you learn to "remote view" without training?
As training is in methodology, and remote viewing is in fact a protocol, then yes, of course you can. How you go about gathering psi data (your method) is really up to you. A lot of people work on getting in a mild trance state, relax greatly, and imagine themselves ‘opening up to information about the target’. As you get subtle impressions, no matter how fragmented or offbeat, write them down or speak into a tape recorder. You will shortly learn that people new to RV tend to add/revise half the data and forget to record the other half. ;-)
When done and looking at feedback, be discriminating about your session. Don’t do yourself any favors with ‘making data fit’ your feedback; but also, don’t be overly critical -- it’s not just a matter of an inexact art, but remember, you are new to this. The point in beginning to intermediate RV is not even so much the data as your learning something about how you process data. Concentrate on what you got right -- how you were thinking or feeling at that time, how the data seemed to present itself to you.
You might find that some data "feels like" it comes "inside quote marks". You might find that this data is usually accurate for you. You might find that usually when you get the impression of a triangle, the target is a waterfall -- who knows?! -- it is different for every person. While some data is literal, much data can be symbolic, and a very personal symbolic at that. It can come as humor, as lines of poetry, as your own responses (aesthetic reactions) to the target, as sudden memories invoked. Don’t judge the data or its form. Accept that you are new to this and be willing to take you get and see how things turn out on feedback.
Data can come in any form. You can hear it; you can hear aspects of yourself talking about it; you can feel it on or in your body; you can perceive it through any physical sense-- although most of the time, what happens is actually a ‘sensing’ that is somewhat ‘inside one’ (I call it "internal kinesthetics") that you know is associated with a certain physical sense, but often is not really getting the data from there. Literal visuals tend to the extremes with most people; they are usually either inaccurate most of the time for a person, or they are very accurate and the primary data a person gets--it depends on the person. (This is a general statement and it varies with a few criteria.) When you get a bunch of data all at once, like a giant ball of interconnected information and experience, this is usually target data.
Learn to sort it out, translate it, not mess it up too much, and get it down on paper, without messing up the protocol (nobody who knows the target should be present during the session), and you’ll be remote viewing.
