A person suffering EA goes to a party or other fun event, but can't enjoy it because s/he is psychologically standing outside of the event and judging it to be pointless, meaningless, stupid, absurd, etc. The sufferer looks around at all the people having fun and thinks, "They're so stupid they don't see how meaningless this all is." Ha ha. Ironically, the people having fun aren't reflecting, and that's why they're having fun.
The only good thing about EA is that it drives some people beyond thinking to a point where realizations and awakening become possible.
