The 27-year-old admitted he had little idea how fast his goals flew in after scoring five times in nine minutes to write Bundesliga history in Bayern Munich's 5-1 rout of Wolfsburg.
A superb strike by Wolfsburg's Daniel Caligiuri had given the visitors a shock lead until the 27-year-old Lewandowski sent Bundesliga records tumbling, including needing just three minutes, 19 seconds to claim his hat-trick.
But he admitted it was a bit of a blur.
"I have no idea how quick my hat-trick was, maybe five minutes?" he told German Sky on the sidelines before being told the official time.
"Okay, it was a bit quicker than that."
It was his best haul since scoring all four for ex-club Borussia Dortmund in their 4-1 win over Real Madrid in the 2013 Champions League semi-final.
"To score four goals in a Champions League semi-final was very important and a big story in my career, but to score five goals means this is another big evening for me," added Lewandowski, who sent Bayern top of the Bundesliga.
Bayern coach Pep Guardiola held his head in disbelief on the sidelines as Lewandowski scored his superb fifth with a turn-and-volley on 60 minutes which gave Wolfsburg goalkeeper Diego Benaglio no chance.
"I've never experienced anything like that in my life! Five goals in nine minutes! Wow!" said Guardiola.
"I may never see anything like that again, either."
Shoot and shoot again
Lewandowski said his goal had simply been to score when he came on. "I just wanted to shoot and shoot again. At 1-0 down, I had to score at least two goals," he added.
"It's been an incredible evening. What a great feeling."
