Dejavu was once described to me as though we are experiencing a current time experience, and the present experience falls into the long-term memory immediately, rather than short term memory, so it feels like the present time experience is being recalled from a deep memory space, at the very same time as it is occurring. 

Being recalled and embedded at the same time.

Perhaps our brain goes slightly off-track while processing information, it hallucinates and creates. There is a feeling that something presently experienced has already occurred in the past, or is in some data space, already waiting to be found. The illusion pits the familiar experience against the knowledge that this familiarity is inaccurate, a glitch in the data.

The method of loci is a techniqueof memory enhancement, which uses visualisations of familiar spaces, often the interior of a family home becomes one’s own ‘memory palace’ enhancing the recall of information. When desiring to remember we wander through this interior space, these set of loci, and commit to memory by forming a connection between the subject and any feature of that locus. Retrieval of the subject is then achieved by 'walking' through the space, allowing memory to be activated.

Somehow, the latent space reminds me of the memory palace, and when we prompt into that space, small embedded particles are ‘recalled’ and transmitted, sometimes with the hallucinations of dejavu. In the dusty crevasses deep within the data, these portraits were birthed.
