The collective unconscious is ever changing, shifting, moving, and traveling like a great murmuration of birds. It travels withing the universal space that is non-physical, that both intersects and is part of our universal reality. This great murmuration is sometimes herded, guided, shepherded, or even funneled both by good and bad beings beyond anything we commonly have a comparison for, tho they may be seen as aliens, gods, angels, or demons. Some of t hose within the murmuration sometimes are natural leaders, pulling away from the group, and others naturally follow, who then have others follow them and so on, pulling the entire murmuration in one direction or another.
To be edgy, simply means to be near or close to the outside perimeter of this great murmuration and choosing not to pull away too far from the main body of the group and become a "leader" which can be for any number of reasons they choose this. Perhaps they are afraid none will follow, or perhaps they simply like the view near the edge, or perhaps it is just circumstances of life that has placed them there.
