Nah, my DJ is just a disorganized mess of words 
what a dream really was doesn’t transpire from a DJ entry. I’ll rather explain that here.
Specifically, I recognized each of the sides I sleep on (mostly divided in right-side, left-side and back, concerning the position of the head on the pillow) has quite the distinct feeling to its dreams, caused by the difference in subjects, how the plot unfolds, if there’s one at all 
, and the way I relate to DC, among lots of other things.
With this, most of the time I can recognize the position I dreamt a particular past dream in, just by remembering how it went, and I could invent new ones in the same fashion 
One trivial example could be, if I sleep hugging the pillow, my dreams will take more of a friendly/romantic side
I’ve also noticed, I gain lucidity by different means and/or different techniques in different sides, since I fall asleep at different rates, and I tend to think in different ways in dreams, depending on the position. But mark my words, there’s absolutely no compartments 
with a little bit more of effort, any tech can work anywhere.
I could go more in detail in this, but I guess it would be quite futile, since I would be entering the realm of subjective experiences. How dreams vary with the position, that’s probably something everyone has to see for themselves, especially since it takes no more than registering what position you did wake up in
