The 19-year-old dismantled Polish qualifier Maja Chwalinska 6-3, 6-2 to become the youngest French Open champion in more than three decades and the first teenager to win the Suzanne Lenglen Cup since Iga Swiatek in 2020.
"I'll be honest, I've done a lot of visualisations before. Not just this tournament, but I've had dreams, I've had a lot of thoughts on how it's going to happen, if it's going to happen, when it's going to happen, where," Andreeva told reporters.
"I would say the feeling in real life is so much better, obviously, than in your dreams. Yeah, it just feels looking at this trophy and realising that this is actually true, and I can call myself a Grand Slam champion."
Andreeva said winning her first Grand Slam in Paris made the milestone even more special.
"I always said that it wouldn't matter to me. A Grand Slam is a Grand Slam. Whatever comes first, I'll be super happy with it," she added.
"I kind of feel pretty happy that Paris came first, because I love playing on clay. I have played almost all my life on the surface. I also speak a little bit of French.
"So I felt like this would be the perfect first Grand Slam for me to come, and so super happy that it happened here."
Even as she savoured the moment in Paris, Andreeva said her thoughts were already drifting towards the next big opportunity on grasscourts, with Wimbledon set to begin on June 29.
"These feelings are extra special. Now I'm already thinking of how I'm going to prepare for the grass season, how I'm going to play grass tournaments," Andreeva said.
"I feel like this thing is a little bit addictive, and I really want to do my best to experience all of this for the second time."
Andreeva's partnership with coach Conchita Martinez has gathered momentum ever since they began working together in 2024, and the Russian added she was delighted that it had resulted in a Grand Slam title.
"It's very special to share a first Grand Slam trophy with her. We've done a lot of work together on the court and off the court," Andreeva added.
"We've also been through so many good moments and some bad moments, especially, I'd say, at the end of last year. Also, she told me she's proud of me. To hear those words from her is very special to me."
