Anyone get that feeling when a market is topping in euphoria or bottoming in despair?

I got that feeling at $225 during the April bubble, at $60 when it flash crashed, at $150 again at the rebound and at the $80 during the capitulation. It's that urgent type of feeling, a vous-devez type of obligation to act. When it's a euphoric tops, it's an alarming sensation of "You MUST buy in!! NOW!" and at bottoms it's a "Last chance to sell! Do it!" kind of heart-pounding focus. In retrospect it's obvious which trade is right but I usually end up making the exact opposite trade.

I'm getting that feeling right now. Anyone else?
