My meditation on TWL as ground has reminded me of a Mayoress of a small town who disappeared. After living a life elsewhere she suddenly surfaced without remembering her other life, or something like that. Such an episode is called a fugue.
It seems to me that TWL can be seen as a fugue. Not the person having the fugue but the structure of the fugue itself into which anyone can fit. Here is Wikipedia:
"A fugue state, formally dissociative fugue or psychogenic fugue (DSM-IV Dissociative Disorders 300.13), is a rare psychiatric disorder characterized by reversible amnesia for personal identity, including the memories, personality and other identifying characteristics of individuality. The state is usually short-lived (ranging from hours to days), but can last months or longer. Dissociative fugue usually involves unplanned travel or wandering, and is sometimes accompanied by the establishment of a new identity.
After recovery from fugue, previous memories usually return intact, but there is typically amnesia for the fugue episode. Additionally, an episode of fugue is not characterized as attributable to a psychiatric disorder if it can be related to the ingestion of psychotropic substances, to physical trauma, to a general medical condition, or to psychiatric conditions such as delirium, dementia, bipolar disorder or depression. Fugues are usually precipitated by a stressful episode, and upon recovery there may be amnesia for the original stressor (dissociative amnesia)."
