I had a dream when i was approx 4 yrs old which showed a nuclear bomb drop off a beach horizon in the middle of the ocean. I saw the flash, then i fell to the ground, sand went in my mouth (i could feel it grit in my teeth)then the mushroom cloud and then felt the nuclear wind. In my dream i was much older but knew it was me. I grew up in pittsburgh, PA, in the woods and never saw a beach or sand until way later.
