Asked about our opponents for what will be the 50th game of our campaign on Sunday and the defender couldn't help but return to the 3-1 reverse at the Madejski Stadium.
Things looked to be going smoothly when Robbie Keane opened the scoring from the penalty spot but two goals before half-time handed the initiative to Reading. They didn't relinquish control and added a third in the second half.
"You tend to remember the defeats and it shouldn't be like that," said the defender. "You should put those games out of your mind but when you step onto the pitch, you want to do as well as you can and when that doesn't happen, you go over things a lot more than when things go well.
"When we went to Reading it ended up a disappointing performance and this is now a massive game for us because we can go four points clear of them if we manage to win.
"Last season we raised expectations and to only just lose out on fourth place was a great achievement.
"We've played a lot of games this season and it's not been easy but now we're pushing closer to fifth and it's getting close. It's up to us to finish in that top six to try and qualify for Europe again via the league."
As for Reading, Michael added: "How they've performed this season and where they are in the league is an absolute credit to them. We know it will be tough on Sunday but it's a home game and one we are all determined to win."
Michael Dawson admits defeats tend to stick in his mind rather than the good times - that's why he's determined to put right November's loss against Reading when the Royals arrive at the Lane on Sunday.
