Is this ASMR?
Old post of mine:
When I tune into the senses and the present sufficiently such the senses become extremely clear and it reminds me of the PCE but isn't there yet, the most salient symptom at the beginning is not "interestingness," but "pseudo-rapture". (...)
Pseudo-rapture is like regular rapture (tingling, rushes, hairs on the skin raise up) but the sense that it is a feeling is very thin. (...) [CLARIFICATION: Because the "inner world" has disappeared to some extent.]
Today, for instance, at one point a person on crutches walked by me, and the clicking sound their crutches made on the ground was so delightful and rich and wonderful that my whole body was filled with immense pseudo-rapture and shivers down the spine for a few moments,

"ASMR feels like a simultaneous stimulation of every nerve in the 'path', starting from the top of my head and descending through my body down my spine and out to my limbs in rushing waves. It feels intensely pleasurable, and I often feel slight euphoria and contentment during it."
It's similar to other adrenalin and excitement rushes, but different in quality. When I have an adrenalin rush, it's almost painful - 'spiky' is what pops in my head - but with ASMR it's much more even-toned. More warm and relaxing - not the stomach-twisting surge of excitement or fear. However, it does overcome me, especially when particularly intense, and it can almost completely incapacitate me at times. If I'm going to illicit type A, I usually do so in a private space, or at least where I don't expect to be interacted with during the sensation, as that would break my thought pattern and certainly decrease the level of enjoyment I got from it.
My current understanding of this phenomenon is different from what I described in my old post, and probably differs in many ways from what is discussed on that forum, but it does seem like the same phenomenon.
I can confirm that it is reproducible by will alone.
I think those who are interested in this phenomenon could benefit from hanging out here.
