Watford stopper Manuel Almunia fumbled Martyn Woolford’s effort in as the 95th minute goal ensured the Lions gained a vital point in their battle to stay in the Championship.
And with Charlton, Blackpool, Doncaster and Barnsley all losing, Millwall are now just one point from safety heading into the final four fixtures of the season.
Holloway said: “It almost looked like it was going to be one them days.
“I always hope the spirit will grow, I always hoped the boys would understand what I’m on about and that looked like it was over and it wasn’t.
“They’re really chuffed with each other and rightly so.
“I thought Watford played well in the first half, they caused us some problems with their movement and the shape of their team.
“We didn’t quite get it right.”
He added: “I knew we had some people on the bench who were ready to come on.
“I knew that team would be a little bit tired and I knew we could have a right good go in the second half providing we could keep believing in ourselves.”
The Lions went behind to a Lewis McGugan goal on 20 minutes before second half substitute Steve Morison took his chance well to level, only for Almen Abdi to restore Watford’s advantage with four minutes remaining.
But Holloway praised his side’s resilience to earn what could be a pivotal point in Millwall’s season.
He explained: “We didn't deserve to go behind 2-1 in the second half, magnificent credit to the players to put a team like that on the back-foot.
“Almunia made two completely out of this world saves, their bench were applauding him.
“You can see he has got that Arsenal quality in him still.
“Maybe Dunney struck his shot too well, the one from Woolford I thought it was in.
“And how ironic that probably the worst shot of the three has bobbled over him.
“And do I really care after what they were calling me at the far end?
“It’s not nice is it, really?”
Ollie added: “I thought our fans were magnificent. I apologised to one of them because Garvan made a bit of a mistake and I didn’t coach him to do that.
“He took two touches and got caught with it. ‘Come on Holloway, you idiot,’ and I said ‘You’re an idiot’, and I didn’t mean that.
“I wanted him to have one touch, so I shouted at Lee Martin ‘Tell him to have one touch.’"
The manager was also full of admiration for The Den faithful who stuck with their side throughout the match, even when things weren’t going their way.
Holloway beamed: “I think it’s about passion, I thought our fans were magnificent, they have been since I’ve been here, since day dot.”
“I felt the lads responded to that.
“At half-time I said ‘They’re still with you, come on, let’s keep going’.
“I had a little tinker putting Morison on and he’s fresh and caused havoc down that side.
“Maierhofer I didn't really want to bring him off because he was causing havoc but I really do believe rigor mortis would have set in the way he’s just gone from not playing to playing.
“I think Lee Martin deserves credit, I think Bailey’s been outstanding.
“If you look at Dunney slotting in playing in the position people wouldn’t think is his, but he looks like he’s grown there all his life.
“I’m just disappointed we haven’t actually got another two points.”
Holloway added: “What can I say, beggars can’t be choosers.
“We’ve made a mistake on their goal, the second one.
“The first one was a great move, so I’m not so worried about that.
“That was us trying to score and we didn’t lock things down again. That’s probably like when I first came and it was too ragged.
“We didn’t make the right decisions.
“You can understand it’s emotional, then it goes and takes a deflection past our goalie.
“It looked like it was goodnight, it looked like a week and a bit ago.
“The great thing about this club is they never go under easy.
“It’s always with a passion and I think they’re very proud of their players at the moment.
“I would be if I was them - and I am at the moment.
“To get eight points out of the last 12, I feel we deserved a few more than that, particularly against Blackburn Rovers.
“I think the nervousness seems to have gone out of us a little bit and that bodes well for the next four games.”
