By means of a terminological clear up it seems evident to me that the terms manifestation, phantasy and reality are all related.
Manifestation is a way in which being can discloses itself, idealism, materialism and endless permutations thereof.
Phantasies are manifestations not considered ‘reality’ but which nevertheless occupy a space that such that they could be considered ‘real’. They do not at a given time hold the power of being interpreted as dominant ideologies.
Reality is just the manifestation that is dominant at a given time. This manifestation will have incoherent borders to the competing phantasies that hover around it awaiting their turn.
