I always hated the psychonaut term “ego death” no ego is dying, nor do I believe that’s even possible.
Instead I internally refer to it an ego disillusion. Psychedelics can cause it very sharp and sudden change to the ego, which as you say isn’t necessarily good or bad.
Personally I don’t find psychedelics to be very spiritual. I think a lot of that comes from the set, setting, and mindset of the user
