What's in a dream?

I had a... pleasant dream yesterday.
It was everything I wanted, and so so real that when I woke up, I was trying to figure out if it really did happen.
Even now, I can still remember everything that happened.
And I can't stop thinking about it.
You know how dreams usually fade the moment you wake, but this one didn't.

And it got me thinking about Inception. The whole another-world-in-a-dream concept.
I wonder.. when you dream about another person, would that person dream about you too? Would you share the dream with that person?
I imagine that in that world of dreams, there would be a lot of floating bubbles of subconsciousness(es). I say bubbles, because I imagine souls wandering when we're asleep. Ghost-like, but I won't go on cause I'm scaring myself.
And what happens is, your bubble happens to bump into another person's bubble, they merge and that causes you to dream about that person. Because they're in your subconsciousness.
Does that make sense?
I just thought it would be cool if this is real. If Inception is real.
Real, as in, dreams could be another world for people. A place where we could do all the things that we never would have dared to in the real world. Lord knows I would do a lot.
Or I could just do it anyway in the real world, if I grew some courage overnight.
