Lone, I have infrequent lucid dreams. I am convinced that at least some subset of dreams are not random. However, that doesn’t imply those same lucid dreams for example are necessarily meaningful either.
In my form or brand of empathy, I have “dreamt” the sources’ thoughts, fearing, or physical pain on about the same frequency that I have received similar messages while awake. So my run rate for material sleeping psi contacts compared to similar awaking receipt is roughly 50%. They feel like dreams to start but they are not. Speaking with a less enlightened crowd, I’d call them “dreams” but I doubt they are but I suspect some who are not tuned to the reality would rightfully intrepret them as such.
I think most dreams lay somewhere between the mundane grey matter‘s exhausted functions and the ethereal or esoteric. I don’t believe all dreams are on the same rank as my own seem to span a narrow varied scale.
After all of that, I will state clearly that the dream or similar state seems to allow for psi connections which are, at a minimum, inhibited while awake.
