At the time the first of those events occurred, I was on the roof of my parents house in Tacoma, fixing an antenna for them. And from there, on a clear day (and it was crystal clear that day), you can actually see Mt. St. Helens. All of a sudden, while I'm sitting on the roof, I see this gigantic (and I mean GIGANTIC) plume rising from where Mt. St. Helens should be. Considering that I'm a good 90 miles away from the mountain you can imagine my awe when I see this plume rise up that covers the entire southern sky -- it looked as if some had let off a nuclear bomb over Ft. Lewis (10 miles south of Tacoma). The plume came straight to the north (or right at me where I was sitting) eventually drops some ash on our cars in Tacoma and covers most of western Washington -- and this was a tiny eruption compared to the big one in May.
It was after this intense visual experience that I began to get volcano dreams, and still get them now over 20 years later.
