Jonny Wilkinson admitted finding it hard to take in after his long-awaited return to the international scene.
Wilkinson scored 27 points on his international return
Wilkinson, who was playing his first game for England since 2003, was man of the match in Saturday's 42-20 win over Scotland in the Six Nations.
"It feels strange - it's been three and a bit years since I've experienced the buzz of an international," he said.
"I guess to be back after some of the feelings I've had over my injury periods feels like a bit of a dream."
Wilkinson had not played for England since guiding them to victory in the World Cup final because of a catalogue of injuries.
Playing for me has always been a nervous experience

"I was hugely nervous, no doubt, but then I really don't think I've ever been any different," he told BBC Radio Five Live's Sportsweek programme.
"Whether it's my 20th game in a row or my first after three and a half years - it's the insecurity of something you care about so much.
"You just want it to go well, you want to win, you want the team to do well, you want to fulfil your role, and because you prepare so hard it does mean a lot.
"Without being there for so long maybe you do feel the nerves a bit more than usual, but playing for me has always been a nervous experience.
"It's something I've learned to accept now but it doesn't make it any easier."
Wilkinson marked his return to England colours with a Calcutta Cup record of 27 points, with five penalties, two conversions, a drop-goal and a try.
The try was controversially awarded by the TV match official even though Wilkinson's foot appeared to be in touch, and Wilkinson admitted he was uncertain about whether he had scored.
606 DEBATE: How significant is Wilkinson's return?
"I never thought I'd be at the centre of a bit of conflict like this, because I don't really score that many tries," he said.
"I thought my leg was close to touching down just before my hand.
"I thought, 'Well, I'm not the one in the best seat. Someone's got a chance to watch this very closely up there in the fourth official's box - he can take his time and get the decision right.'
"So when it was given I guess I thought, 'That must be it,' but it's not really something I care to reflect on.
"I enjoy the fact I remember being involved in the game and I guess my sights are forward now."
