Sergi Roberto thought he had dreamt scoring the match-winning goal which sealed one of the most remarkable Champions League comebacks.
Barcelona wrote themselves into the record books with a stunning recovery against Paris St Germain on Wednesday night.
Trailing 4-0 from the first leg in France, Barca scored three times late on at the Nou Camp to snatch a remarkable 6-1 win on the night and progress to the quarter-finals 6-5 on aggregate.
The sixth and crucial goal for the Catalan club was the 25-year-old defender's first goal for Barca this season, and Roberto said he could barely remember how it actually happened.
"When I woke up, I wasn't sure if it hadn't all been a dream," the Spaniard told Barca TV.
"I didn't see a thing until the ball went in. I could see that (Gerard) Pique hadn't reached it and I threw everything at it. It went in and we all went crazy."
Luis Suarez's close-range header gave Barcelona the perfect start inside three minutes before an own goal from Layvin Kurzawa halved the deficit by the interval.
A penalty from Lionel Messi five minutes into the second half had the stadium rocking, only for Edinson Cavani to crash in what looked to be a crucial away goal just after the hour mark which boosted PSG's advantage.
Neymar, though, netted a superb late free-kick before levelling the tie with a last-minute penalty to get the Barcelona fans dreaming of the impossible once again.
That became a reality when, with goalkeeper Marc-Andre ter Stegen having joined the attack, Neymar lofted the ball into a crowded penalty area.
Roberto stabbed it past Kevin Trapp to spark wild celebrations on the Barcelona bench and in the stands, while PSG watched on in disbelief.
"We could feel that the Camp Nou was buzzing. We could really feel the fans' support. I simply have no words to explain how it felt," Roberto said.
"I had always dreamed of scoring a goal like that and being a lad from La Masia made it all the more special. I've worked so long to do something incredible like this for my club.
"We gave it everything. Our attitude was spectacular. It's a night that will always be remembered, like the one at Stamford Bridge when (Andres) Iniesta scored. We made the impossible possible."
Roberto also praised Barca head coach Luis Enrique, who has announced that he will not be with the LaLiga club next season.
"People spoke about how hard it would be for someone to come here and get us to win after everything that's happened before. But Luis Enrique has shown that he's made to be here, and the team has been 100 per cent with him to the end.
"This comeback has given us new life to deal with what we have left of the season."
