That feeling where you're in (or observing) a densely populated area and struck by the fact that each person you see is also experiencing that moment through their own lens, which contains a lifetime of memories, dreams, anxieties, love, loss etc. That profound "we're in this together" universal empathy feeling. Is there a word for that? I experienced it while delirious at the airport/flying over city lights. Conversely, there should be a word for that profound sense of alienation when you're in a densely populated area and get the sense that your own experience couldn't be further removed from the people around you. I experienced that one today while doing everything I could to avoid shopping cart collisions at Costco. I nominate emphory (also emphorial state) for the first, and antiphory (antiphorial state) for the second.
Also, that weird ticklish sensation your guts experience when swooshing through the air on a swing/rollercoaster. I'm calling it swingasm.
