I have managed to have some communication on a number of levels. But before we go on, I think having seen many peoples experiences I need to define that I am talking about communication in that place of breakthrough - where reality is fully replaced, and I have my eyes closed and no sense of body. And the reality seems fully solid i.e. not just lights and geometry (which I think is somewhere part of the way there), or some form of analogy to this reality - where it seems entities appear like us and speak.
I have a theory that there are a few places you can go, but I am yet to work out a distinct methodology or experiment on other methods than my consistent one. I am tempted to start a thread about eyes open vs eyes closed (unless there is one already) as well as full body relaxation vs. sitting up.
Anyway, I have tried talking with my mouth - I was told to shut up. I have gone through a number of methods of trying to communicate. I have discovered that the primary issue is linguistics, we even think in our language of words, throat vibrations, and mouth shapes.
Our earthly language is useless, both in our head and through our mouth (although there is something interesting about throat sounds and tones - and as you are all saying there are those quite experienced on this here). I even have found that having words continually resonate in your head blocks actual communication.
Anyway....
In my experiences I have been invited to "communicate" and I think I know how it works there (or does for me for what this is worth to anyone else), I think you all know. Its just not verbal, I'm not even sure that over there there are objective statements that can be transferred - its more subjective feelings. But the subjective can be communicated, every entity even yourself is open to examination - you can look into them and see what they are and sense their intent. It feels very invasive when they do it to us, and I think it is seen as brain surgery.
I was invited into a library, or a party or something that was both. The entities there opened themselves up to me and I could move from one to the other and really look at them, the closer in I looked the whole universe of them opened up. It was made clear to me how this works - not in words of course but just known. I am not sure if consent is necessary, and I am worried I may have overstepped my invite in one case and an entity was quite annoyed with me.
They do also try to communicate with us verbally, most tend to be pretty bad at it - but probably not as bad as we are at their communication.
To talk I just project my desire - just by feeling it, it is known by any that look at you. Its like that thinking you can do if you don't verbalize in your head.
This is of course all my crazy thoughts on the matter, but I have a strong "knowing" feeling of some of this which I put down to communication. I am either going slightly mad, or I'm on to something or this is just a sequence of odd trips that are there to tell me something and this is of no use to anyone else.
I've also seen entities a number of times who were clearly children, or should I say young developing entities, often with a mentor or parent - which opens a number of questions about the nature of the other place.
I speak as if it were fact, but indeed this is just the insane ramblings of my ego - but my inner self seems to be nodding.
