Goalless at the break, the Reds scored three excellent goals after half-time to continue their stunning revival since Freedman's appointment.
The Scot, who talked after the game about the break clause in his contract that allows either him or the club to walk away from each other in the summer, has presided over a Forest side that is playing some superb attacking football.
But he told the official website: "The last 15 minutes of the first half epitomised what we’re about.
"Reading were certainly the team on top. We needed to show resilience and organisation in our defending. That’s what really won the game today."
The bandwagon rolls on for the Reds to Charlton on Tuesday night where the hosts will also be confident after a 3-0 victory of their own at the weekend when Huddersfield were despatched at the Valley.
A £5 ticket offer boosted the crowd to over 25,000 and manager Guy Luzon said afterwards: "It was very important for us that today with a full stadium that the fans and the people around the club would go home with a good feeling."
