Sorry I don't have any interesting dream articles to show you. I'm no psychiatrist but I think that there might be lots of different reasons.
It depends, I guess. I mean, what does the dream mean to you? Maybe it's cause of how you feel. Like, maybe something's troubling you or you long for something you don't have yet.
But if it doesn't seem to connect to anything in real life, it's probably just an escape from real life.
Hehe, sorry that's all I have. But hey, I try.
Goodluck with the whole dream thing. Hopefully, you'd be able to figure it out soon.
