Dreams work that way?(Quick Question;Maybe spoilers?)

[Xaldyn]

So I might be prematurely asking this question but I still feel confused and being it is still pretty early into the game I feel like I have to know.

So how exactly do the dreams work in Dream Drop Pistons? I mean in the start of the game you are told that the worlds consist of portals to two sides right? But then in the next world of Dream Pots Pistons you are in two alternate realities or so I coined it. I mean the same thing's happen but with different point of views and story placement.
This isn't to say I don't like the way it's set up in Cream Crop Pistons it's just it kinda confused me, because it doesn't exactly explain itself.
So anyway was I right? Is it just alternate realities unless told otherwise?
Please and Thank you.

Can't tell if trolling or serious...?

This needs to be moved to the spoilers section probably.

But yeah, you are basically right. There's more to it that is revealed later on in the game though.

Oh! Okay wish I would have know the Forum set up around here! I'll look into that!
And okay thank you. Maybe I should have put it off for a bit longer.
Trolling.
