Sean Dyche admits he was not surprised Watford came from behind to beat Millwall 2-1 to claim their first home win this season.
Liam Feeney gave the Lions the lead when his cross deflected off Lloyd Doyley midway through the second half.
But Carl Dickinson equalised with a fine strike from the edge of the box before Craig Forsyth claimed the late winner.
"It was a strange moment because you just can't believe what you see," said Dyche.
"I think it's fair to say we dominated the game from start to finish and when that went in, it's one of those weird moments where me and the staff got our heads together and I said 'we'll win it' because you can't keep dominating games [and get nothing].
"Football evens itself out over a season."
Dyche's instinct was justified when Dickinson equalised with a fine strike from the edge of the area on 77 minutes after a corner had only been half cleared, before Forsyth capitalised on Paul Robinson's misplaced header to score the winner with five minutes remaining.
"I've stated a couple of times I'm very surprised we haven't had a win here already," Dyche added.
"I believe in what we do, the players clearly showed tonight they believe and I'm most pleased for the fans because they've shown great belief in the turnaround at the club.
"They know there's been big changes here, with big players leaving and good players coming in and certain guidelines, and I think they're really realistic and they've been fantastic in supporting both me and the team.
"It's a big one for them tonight, it just clears it out of the way, but we're not getting carried away with it, the obvious fact is we got Southampton on Saturday but we must enjoy it because we thoroughly earned it."
Feeney's fortuitous effort may have ended the Lions' six-game goal drought but they have now taken just two points from the last 18.
Millwall boss Kenny Jackett said: "There was a lot of spirit there tonight and we really dug in and I thought we deserved something.
"I didn't think we got the best of the decisions. Danny N'Guessan's goal in the first half, flagged for offside, I had a reasonable view and I thought that was a tough call, and I thought we had a good appeal at the start of the second half for a penalty for handball.
"It's quite a tough one to take in terms of those things but we did show some spirit today and we're obviously disappointed but it was a better performance then it was against Derby on Saturday.
"We have to take that spirit, find more going forward there is no doubt about that and if we can do that there's results in the future for us."
