What does it mean if a man says he feels like there is something he would like to cover with me soon and that it is nothing bad just been on his mind?

After I hanged out with one of my friends over coffee, he flicked me a text that he feels like there's something that he would like to cover with me before Christmas, that is was nothing bad just been on his mind., When I inquired more about it, he said that it was just some personal stuff he wants to share or just something about him he wants to share which is good. I am a little bit confused and uneasy about his message as normally when people share things, typically it is not good. And if it is key milestone stuff - having another baby or moving jobs or changing cities, he could have brought it up over coffee and I do not feel like these things are personal. What do you think this could be about? It is super odd.
