What's weird is that in 1989 when I was a teenager, I had a dream (believe me, germ warfare/bioengineering/sci fi was not on my mind as a California teen girl) that there was an airplane overhead emitting an airborn, gaseous, chemical trail and people were breaking out in itchy welts all over their legs and body.
Funny, you should mention this. I was listening to a radio program on dreams, the other day. The speaker was saying how we are able to travel to the future in our dreams. Also, that, then one is able to use that knowledge to one's advantage. Myself, I have night terrors and wake up before the dreams get going. He advised to stay asleep and face the dreams. S%$#, guess I'll give a go at facing the night terrors.
