Though this usage continues to be widespread, the term, "etheric travel", used by some later Theosophists, offers a useful distinction. Some experients say they visit different times and/or places:[41] "etheric", then, is used to represent the sense of being "out of the body" in the physical world, whereas "astral" may connote some alteration in time-perception. Robert Monroe describes the former type of projection as "Locale I" or the "Here-Now", involving people and places that actually exist:[42] Robert Bruce calls it the "Real Time Zone" (RTZ) and describes it as the non-physical dimension-level closest to the physical.[43] This etheric body is usually, though not always, invisible but is often perceived by the experient as connected to the physical body during separation by a “silver cord”. Some link "falling" dreams with projection.[44]
