It's called a repetetive dream and you need to pay attention to those- usually there is a message u need to heed in them.
strange dream, maybe he is hiding a kid from u- just my first thought- or he's gonna hear about a child soon. I rarely have werid dreams like that- mine are 99% like real life- I'd be scared to sleep if i dreampt my bf was flying down a hall with wings scraping etc.
Hm.. Your mind still yearned for it.. So it pulled back any scarce remains. Though, the feeling was altered somewhat, I firmly guess.
Well, still. The dream was sought important by your subconcious.. Take it in.. like a stray.. back again.. the next day..
