Mine your mind II: Dreams
This was (almost) exactly what I saw... As well as I can recall... I stood on some sort of dock or warf overlooking the sea in a dream. A pod of whales simultaneously surfaced and shot sky high jets of flame from their blow holes! I turned toward the elderly woman beside me "are you seeing this?!". She slowly shook her head no. I suddenly realized that I was also not seeing this. In fact I was dreaming, the scene had been generated there in my mind, concealed from the world.
