RubberSpacing (verb) the act of inducing, focusing on and enriching a womb-like environment, sensation and mindset. The inducement of a dreamy state of profound comfort and reverie, not unlike what we probably experienced while in the womb. It is often experienced in T/E (“Total Enclosure”).
Sensory deprivation and immobilization are environments which may help induce RubberSpace.
The ability to meditate conventionally may also be a foundational skill which may help one deepen and enrich the RubberSpace experience. E.g., counted breathing coupled with scanning may help meld the two as an aspect of RubberSpace
