The dreams are sometimes this complex, yes. This one in particular was pretty hard to remember, especially because I didn't have the opportunity to write anything down.
Me remembering the dreams... well, it's like this: When I wake up, I remember a few ideas, images, bits that are mostly held together by feelings and a sense of things. The narrative I wrote for this one was what happened in the dream, but probably not in so many words. I remember Colin Farrell describing the things to me, I remember my hand gestures through the glasses, I remember basically him showing me an example, and I remember his family's distress because he chose to be somewhere else and not with them.
The rest I have to sort of work in there to provide a narrative that makes sense. It's me remembering the dream, and trying to describe the rest. There may be some artistic license, but I still had a crazy dream where Colin Farrell was a bad father.
