Hi Oceanic00! I'm not sure if I can categorize this as something ethereal but I have my own special world [where I am a superhero and I am always out to save the universe] that I always go to in my head, especially when I am about to go to sleep. It keeps the creative juices flowing. Cigsmoker [Sam]
Music is frequently playing in my head, kind of like an internal soundtrack to my life. Usually it's some "ear worm" from a piece of music I heard recently.
It's not ethereal, but I have a summer home somewhere in the back of my head. I try not to get too wrapped up inside myself though. It doesn't work.
