Lately I have been reading and writing a lot about psychoacoustics acoustics and sound and space.
Yesterday as I was falling to sleep I heard two male voices talking while I had my eyes closed. I did not listen to the conversation instead I was listening to the reflections of their voices of the surfaces in the room surprised at how precisely I was able to locate the positions of the voices and the room they were situated in. I was aware that I was dreaming and surprised that a dream could evoke not only voices but also position them in space.
Waking up again the room was empty.
