Last night I had this dream, it wasn't lucid, but it was weird and very emotional. It was completely dark, and open space. I was only a consciousness, and knew I had no corporeal body. I knew there were others around me and they were all only consciousness as well. It seemed we were all stacked or arranged in certain ways but we knew the space that contained us was endless vastness. The feelings that predominated were abandonment, sadness, and fear that this is all that is, almost like the idea of purgatory after death. There wasn't any talking but we telepathically knew the emotions of one another. When I woke up, it left residual sadness and almost an idea of I hope that isn't how it is after death because that was so horrible. Was this a NREM dream or was it just a bizarre normal dream?
