After scoring 39 goals in all competitions last season, there was speculation that Aubameyang would leave Dortmund in the last transfer window.
"I think there was interest from Real Madrid, but it was more distant so I didn't get too carried away," the Gabon star told the monthly Onze Mondial, according to Efe on Tuesday.
The striker admitted the statement he made about Los Blancos as he said: "I was asked in an interview 'What is the club of your dreams?' I replied 'Real is the club of my heart and I made a promise to my grandfather to play there one day, I hope it will happen.'"
"So it's just a target, I still have time. If they want me, they will come," he added.
The 27-year-old also revealed that his father held talks last summer with Manchester City and with Paris Saint-Germain (PSG).
"It's true, there was contact," he said when asked about City. "My father held talks with the club, but in the end there was nothing concrete."
The former Saint-Etienne forward also spoke about the interest from PSG, saying they had been in regular contact.
"They're still a big team and I think they'll still be Ligue 1 champions this season. But there are one or two teams who could annoy them," he commented.
"At the end of my first season in the Bundesliga there was contact. And the next summer, too. In fact, almost every year. [PSG] took it poorly, it didn't happen -- that's all I can say," he said.
"I don't especially want to return to France immediately. But it's true that PSG have the ambition to win the Champions League, so they could be interested in a player like me."
