NO....you simply return to this dimension...LOL@ "simply"...

when you abruptively get woken up during a meditative state- its alittle uncomfortable and you are disoriented...this i know from experience..even when the "return" is natural and at will, you take care in re-awakening to this time and place...meaning coming back slowly and upon wakening stay calm and relaxed for a few moments. the brain waves induced to achieve this- are not normal functioning patterns that allow us to be in our conscious state of mind during normal physical every day lives
...theta and delta wave patterns must be attained- delta being the deepest and required to AP...
we live in the "beta" range- this is normal brain wave pattern that gets us around during the day and to our friends BBQ on time.
the "alpha" range is when we are starting to balance the brain waves out- this occurs at pre-sleep or drowsiness...
