It can be frustrating at times; we close our eyes to go to sleep and we cast ourselves back to these places. We feel genuinely feel the pain of regret not being there anymore. It can be like the grieving process.
It's actually like we are still there; or have just been there; especially if we capture a thought process that was last perceived when we were at this location. It is very much as if we are linked through time with the location, the memories are so vivid. Well, with this existence being a virtual reality conceived from our thought processes, it is possible that there is still an open link to the location; our thoughts are externally active in multiple realities simultaneously; so why can't it be that we have just touched on the vibration of that place in that moment, and are actually there on another altered state of consciousness? We feel the energy of that interaction, and register it in this moment, on this dimension as a forgotten melody?
