In recognising the fictional in life (in living) for what it is (playful, pretence, life-defying, life-denying) we are constantly drawn to the non-fictional circumstances of our actualities.
Sometimes our act of living is a mundane interaction, e.g. tidying, organising objects by various systems e.g. aesthetic; or a social (physical, body to body) interaction.
Any act outside of fictional (non actual) mundane (body to world) or social (body to body) interaction is problematic.
It is in this non-space that there is a direct contact with mortality, but also with the non-mundane (the world apart from the normal human experience of world) and non-social (humanity outside of the normal social experience of humanity).
The non-space is a self-consciously futile space and a space void of a context that could remove it from futility whereas the mundane and social spaces are unconsciously futile (due to their boundaries) but non-futile within the context of themselves (within their boundaries).
The non-space is a futile space (at least for a human being) and yet it is a necessary space due to our self awareness (awareness of non space) that often prohibits us from the mundane and social spaces (although all three spaces are physically the same space, the only space where we are able to exist)
The non-space is a space in excess: while we are in this space nothing is tidied and no friends are met. And yet the mundane and social spaces are excessive to this space. Their excess (of mundanity and of sociality) necessitates the non-space.
The non-space seems to hold nothing, but is exciting for its actuality, whereas the fourth space, the space of fiction, seems to hold everything but is not real (except within its own bounds of fictional agency, the bounds of its media and conceit).
In the same way the non-space has no context, it has no conceit and no medium.
Because the non-space has no medium, it is understood that fiction by means of its own media may gesture towards this other space, this non-space. This is never the same as inhabiting this (non-)space. It is only to inhabit the fictional space.
For example, the space of this writing, of this particular writing and reading, is the fictional space, despite its earnestness. There is no conventional (i.e. fictional) writing in the non-space.
