Darren Way’s side suffered a first league defeat since the opening day of the season on Saturday when Swindon came to Somerset and left with a 3-0 win.
The game marked the first time the green and whites have conceded in seven matches and ended a six-match unbeaten run.
Looking to boost their record of one win, two draws and one defeat at home in the league, Dickinson wants a quick return to previous form.
Speaking to BBC Somerset, he said: “We want to make sure that any time a team sees they’re playing against us that they’re going to think ‘we’ve got a tough game coming’. We want to be like that all season.
“We need to make sure we’re doing that more often than not. Especially with our home games, we want to make Huish Park a fortress and a place people don’t like coming.
“If we get back to what we’ve been doing of late, we should do well enough to take the three points from what will be a tough MK Dons team.”
The 31-year-old has been an ever-present since signing in the summer from league rivals Notts County.
Quickly setting into life in the South West, the left-back admits Saturday’s performance fell short of recent standards but is relishing the chance to go fourth in the table with a win against the Dons.
“We’ve been on an incredible run but we let ourselves down a little bit which is difficult to say considering how well we had been doing.
“We weren’t anywhere near the standards we’ve set ourselves of late but we’ve got a chance to put it right quite quickly.
“Everyone wants to be up and around the top of league, it doesn’t matter when. It’s most important to be up there come the end but it’s always nice when you see your team’s name up around the top of the league but we have to make sure we put the things right that went wrong on Saturday first.”
