I've not personally any experience with it, but the 5-meo experience sounds like it sits a little more in the singularity category - which depending on your world view might be closer to objective base reality.. DMT being more of a simultaneous one-ness/abundance of form.. with one's personal journey sometimes the focal point.
If I were to try and get around it in gnostic terms, I'd probably categorize hyperspace itself as the 'pleroma'.. the realized images of the One (though this itself is also regarded as being both singular and plural).. and the occupying presence perhaps the Sophia ..
.. 5 meo sounds like it approaches the Monad (or One/Father) .. no-thing..
but hey.. those are just a bunch of words
(sorry hyperspace, for trying to categorizing you)
