That is weird about the buzzing sound. Once in my early 20's I was living alone with my young son and I was going through a terrible depression. I fell asleep and I can't remember the entire dream but I remember seeing myself. I was sitting in this very dark place. I think the bible was laying beside me. I looked pathetic. I appeared to be in a gown. I guess like a night gown. I was there and I was so depressed I was sitting with my back up against something but all you could see was darkness around me and my head was slumped over in a deep Depression without hope. Then I heard this buzzing. It was the oddest buzzing noise. It got louder and louder and very intense! Then I sensed hell open up beside me and the buzzing was actually made by millions or trillions, I don't know it was just a huge number, of dragon fly wings. I can't remember if I heard the voice of God audibly in my dream or if it was his words just impressed upon me but I remember feeling it was a warning from Him that if I did not read it I would end up there and it had something to do with my depression. I remember being extremely frightened after that dream and not understanding how not reading the bible would send me to hell. Anyhow to this day, I am scared of that buzzing noise. And I couldn't stand for many years dragonfly's. I would not by a piece of clothing or jewelry with a dragonfly on it. And even now, though I am less affected by it, I do not prefer dragonfly's as I once did before the incident.
