Ramos has not played for his country since March 2021 and was left out of the squad for the European championships last summer.
That disappointment followed an injury-plagued campaign in his final season with Real Madrid and it continued into his first season with Paris Saint Germain, making just 12 appearances in Ligue 1.
The 36-year-old looks set to better that tally this season, making 11 appearances in the French top flight and adding five more in the UEFA Champions League already.
A veteran of four World Cups already, Ramos will be looking to add to his 180 caps for Spain when Enrique puts together his roster for Qatar in a few days time after finding some consistency with his fitness.
"Everyone knows what it means to me to defend the colours of my country," Ramos said at a news conference ahead of PSG's Champions League fixture against Juventus on Wednesday.
"After a difficult season, I feel good again, I'm playing again and I'm available. I still hope to return to the selection, and I dream of the World Cup.
"But we have to wait and continue to play at the best level to convince the coach. I hope I will have the chance to play in another World Cup.
"Last year was difficult. I was injured, I had to adapt after spending most of my career at Real. At no time did I think it was the end of my career. It was a challenge.
"Last year is forgotten. There have been changes and I'm happy, I'm totally adapted to Paris and I'm hungry for titles.
"If I think it is over, I will stay at home to take care of my children, but I think I can last a few more years at the best level in football."
