Do these entities purposefully use words that you do not know or do not normally use in order for you to realize they are real?
In my case it is a big YES, every damn time.
I have 2 ways:
1.1) I hear words that i would not nomally use and 1.2) these words or phrase comes fast without me thinking of it. 1.3) these phrases or words have to make sense in the context.
Example: today i heard the word "confabulate", other day i heard the word "advent"
Or names of entities i did not hear before in my life and after research they exist.
2) the results or materialization that come after those words.
For example: Prince Sitri regarding my petition "told me": "Beware things are going to change from now on, radically". And he was right.
From there i know it is not my ego who is talking. If i hear words that i usually use i take it carefully, and i totally discard things that are recently seen. For instance, if i am reading about certain things and a word comes up to my mind regarding that thing i am very careful if i take it or not.
I am still such a noob and it will take years to master this. How is your experience? Do the entities use words you usually would not use in order for you to realize you are not talking to yourself?
