I think this was about imagination held back. Not sure anymore.

Will-o-wisps of wonderment - all those colourfull fantastic energetic ideas that can be happiness in life or adventure, things like that.

For sure they dance around - so many exciting things to grasp and do in a lifetime, happy to have opportunity.

Then, too, be there strings of twine - all the parts of life that bring one back down to earth. all the reasons that each little dream and idea just isn't quite possible just yet.

To leash obsidien'd crown - the crown id of course the mind; a crown, golden, noble and grand, an echelon the mind is wonderful and beautiful. "obsidien'd" to be turned to dark cold hard stone, thought slightly translucent. An obsidien'd crown is a crown that can be seen under an impenetrable layer. all your hopes and dreams stuck an unreachable.

so it is manic a beatifull excitement and happiness as well as a some how 'noble' depression.
