When doing long travels on bus lines I put myself in a relaxed state then close my eyes. I can still hear any sounds made in the bus, but time "disappear" and I "wake up" from the relaxed state when the driver suddenly announce over the speakers that we are arriving at my designation. I also usually do this when resting rather than just sleeping for an half hour when needed.
Which state am I in during that period? (Yes, I know, relaxed...
)
