Tonight I dreamt I was sitting in the old catholic church which I was forced to go to as a child. But I was there as an adult. There was a group of people and we were sitting - untypically for a church - in a circular arrangement facing each other.

A girl (unknown to me) says that she thinks that outside the sound of some planes or other flying machines makes such a nice soothing and calming sound. I also hear it and agree with her. I wake up. I hear the sound of my hifi audios I had turned on during sleep. It was a HemiSync Lucid Dreaming sounds. It does not really sound like planes in the sky, rather like rain or a storm. Still it has a deep and permanent sound carpet which is - of course - soothing and calming. I KNOW that "she" referred to this sound which I also heard in my dream then.

This is interesting. A dream personality referring sth (a sensual auditory input) that is going on simultaneously in the physical world around the sleeper. Maybe she wanted to 'wake me up', but not from my sleep but rather in the dream to get more lucid.
