Real as in how Jungian archetypes are "real", except these archetypes are able to act upon the world through their hosts, and an advanced enough idea can be self-referential and have the facilities for structured evolution and something which looks like intent.
These forms are non-biological in nature, but our psyche operates on them. Zodeaism can be seen as an extension of ideas such as Jungian archetypes and Friston's free energy principle.
