yup i think as a super set 'entities' works well enough
[in that it characterises 'them' as having a semblance of 'individuality']
there are [from my experience etc] different 'classes'
individual entities and 'hive' or 'homogenous' entities [i.e where while they appear in some sense as individuals they are also interconnected or 'linked' into a continuous connection with the others].
re shapes of entities -
it could be useful to attempt some form of classification system to relate those with continually adjusting shape [as a multi-dimensional shape would would appear to as it moved through the perception of a lower dimensionally constrained perspective [sensu a Flatlander viewing a spacelander passing through flatland]].
this would add an extra field to the more concrete shapes.
i don't really know how, but i'm sure someone will have some ideas.
maybe also attaching if the entities had emotions or similar expressions [in general i find the entities do not experience emotions (fear, anger, joy etc) and find them interesting and or quaint].
they often seem to have a form of e.g love or compassion though
anyone with psych experience know if there are classifications of difference re these?
perhaps also defining similarities and differences in sub breakthrough (eg flat images of entities, mind/consciousness interactions) and breakthrough (greater depth of entity images, mind/consciousness interactions)
p.s. i met a really friendly sea cucumber type (female?) entity once.
really really friendly
anyone else caught up? [green body, red/orange for the tentacle type structures]
if so say hi.
