DMT no. These are all coming from reports (and from Terrence himself) which I have no problem believing since I've witnessed my fair share of weird shit in general.

I've only done my share of LSD in the past, which by comparison, seems quite tame and merely "psychological" than DMT.

I wonder if you would consider it heretical to question whether and how well Terrence can differentiate between what he does know and what he does not actually know?

For example, you used a rather non-rigorous descriptor, "weird". What constitutes a weird phenomenon?

Can we subject said constituents of a weird phenomenon to the same kinds of validations we can make about known true facts, i.e. observable existent things?
