Haven't been here for a few months so I don't know if this has been discussed here already. But anyway I'd like to share my two cents about this matter.
Just today I've had a vivid dream which felt pretty real to me: I was driving a car on a beach and a while after I hit the car into the sea (I don't know why but I wanted to). In that moment I was trying to hold my breath, which was very uncommon (since childhood in dreams I can breathe underwater) and really fascinating, too. Then I swimmed off the car and out of the blue there appeared some big sea creatures that really don't exist and all that had some crazy story which doesn't make great sense if you consider the story in awaken state.
All I want to say is that while it was very vivid when I was dreaming I still consider it as "a dream experience only" because in awaken state my memories of this dream are not so clear now (unfortunately: Because I loved it, fortunately: My memory would be very confused, I guess). I think that "dream logic", the logic that doesn't make any sense in awaken state but still is so much enjoyable (I know I enjoy it) when someone sleeps, could be some sort of compensation for the fact that we are unable to recall the dream experience (even the very vivid one) in scale we wanted to, so our brain makes dreams a unique experience and the way it's doing it is by "bending" common logic, which is a way that is truly fascinating. The other way is making the dreams so vividly beautiful as reality could be and sometimes it's by both ways, like in my today's dream.
I hope I didn't confuse anyone. :) I will be happy to read any opinions on this topic. This thread isn't locked, I hope.
