There is a rather sharp distinction between

(1) being aware of one's being in a dream and disclosing it to other persons during that same dream; and

(2) being aware of one's being in a dream but not disclosing it to any other persons during that dream. Another seemingly conceivable distinction might be

(3) being aware of one's being in a dream but not having anyone else present -- but this 3rd alternative would seem only to arise when one is lacking in the intent to disclose the fact of being in a dream to anyone whom one might encounter there anyway (whenever one would wish to disclose this fact to others, the wish to do so would apparently cause them to become present). What might seem other possible

(4 etc.) distinctions (such as communication of the fact of one's being in a dream by some other method that the person communicated being present -- whether contemporaneously via telegraph, telephone, or telepathy; or in future potentiality as writing a message, such as an epistle or a blog-posting -- are somewhat intermediary between (1) and (2).

Whereas subtypes of (1) may most productively be distinguished on the basis of responses by the addressees (dream-persons told that this is a dream, and that they are bream-beings),

subtypes of (2) may be most readily distinguished on the motivation of the dreamer (why the dreamer abstained from communicating the fact of this being a dream and bystanders being dream-beings).

[The distinctions among various types and subtypes of lucid dreaming on the basis of communication of non-communication of the fact of dreaming to dream-being present or not present, must constitute a subject-matter worthy of far more extended treatises.]

The reason why we bring this matter up, is long personal experience, extending over some decades. There passed quite a number of years wherein our dream-experiences were severely handicapped by our failure to cite the proper terms of address (in informing the dream-beings whom we encountered in our dreams that this was a dream, and that they were dream-beings), with such lack of success that those dream-beings would never volunteer to inform us that this was a dream and that they were the dream-beings.

(As for others' similar predicaments, we have not found very definite explanations -- some lucid dreamers write that they are informed by the dream-beings in a dream of the fact that this is a dream : but how they managed to attain to that status of respect as to be so informed by the dream-beings in their dreams, has not been adequately written about to our knowledge. So as to attempt to remedy that deficiency in the description of how dreamers can attain to the status of respect in the dream-realm as to rate being informed by dream-beings of this being a dream, we render an account our own personal experiences along this line.)

When, however, after those years, we started in our dreams to cite the appropriate terms of address [as essential in the dream-realm as in heraldry, and as formal and rigid], then indeed we promptly attained the sought-for success : thereafter the dream-beings would inform us that this was a dream whenever we doubted, eliminating our doubts with their firm insistence that this was a dream. (Thereafter we found scope for progress openly available, a progress which was able to extend its benefits into other states of consciousness -- we found the effects described in texts of shamanism to be confirmed.)
