I hate seeing "the religion of peace" bullshit here.

99. CT scans a very recent technology in human history

Prior to CT scans there was no way to verify
or empirically document dreaming.
So should we leave the door open to other
phenomenon of experience, such a spiritual
or religious experience?
Will science will eventually catch up as it has in dream research?

The idea that cross-cultural comparisons can be used
to validate dream experience could be given the same
weight as "spiritual" experience.
The main distinction being that everyone can agree to the
parameters used to define a dream, whereas
a spiritual experience lacks such universal agreement.

For my purpose I use "spiritual" in the sense
of "Trans-personal Experience" because that is
a common feature of many living religions.
A trans-personal experience in psychotherapy is
often described as a spiritual experience.
The transcendence of personal Ego, the identification
of self with SELF, is an often identified as the intended
result of religious or spiritual discipline.
So there is arguably, cohesion across individuals or cultures.
