Dixon, who made his first start under Powell in the 2-2 draw against Ipswich Town last time out, has now targeted three more points against Nottingham Forest on Saturday.
"Things are really positive and there's a buzz about the place," the Scotland international is quoted as saying by The Huddersfield Daily Examiner. "The manager is very positive, his coaching staff are too and I think that's beginning to show in our games.
"It was great to get a point at Ipswich, which is never an easy place to go, and we showed a lot of character to come back from 2-0 down and, ultimately, we could have won because we had chances.
"From my point of view, I was just very happy to be back in the team and, hopefully, I did enough to make sure I stay there for Saturday."
Huddersfield are currently 17th in the Championship table.
