My conclusion is that people focus on the wrong target. Ego death is easy, but being fully aware of it is not. As you pointed out, when it happens, we don't notice and are just left with doubts or concepts. Little by little, we train in recognizing what's happening. The secret is to relax into it and not resist. It's like the first and biggest lesson of psychedelics, which can lead you all the way. Who is experiencing ego death?
Ego-death is something that sounds fantastical... until it happens, most of the time.
I may be an exception to certain observations and it's why I have some of the view that I have. We have certain expectations for certain experiences, in this case, ego-death, that might show up in different ways for different people.
However, it doesn't detract from the conundrum that people actively seek it and this is somewhat odd. A simple way I come to think of it is the ego is the part of self that cares there is a self. More than an experiencer, it is preserver, a preserver of the thread of consciousness that is "you." That said, the stripping of the ego, as the preserver also in many ways the controller, is always fraught and a fight... unless one has perhaps a well-trained ego
My third DMT experience lasted around 55 minutes. How? I don't know, that's beside the point. The point is that this was maybe my second "ego-death" experience (first was on 7g in a theater watching Avatar in 3D). I can actually recall it (which feels "triggering:" my heart is racing, I have goosebumps, my hair is standing, etc). I can see parts of it in my memory. During the come-up, very early on in the experience, I was convinced I had died. From that point everything that made "me" me was viciously stripped away. "I" ended up in a "place" surrounded by other "souls." There was still thought here, but not really identity. For example, there wasn't a "how did I get here," but a "what is this place" there was an aspect of my being that could reflect on itself, but would quickly be removed from it. It "didn't care," for lack of better words. As I think about it, that's why this is so hard to describe; it was beyond words.
But every time, there is a shock in "coming back." It hurts, sometimes to the point it makes you puke...
One love
