When I was younger, I used to have these extremely accurate prodromal dreams. Every time when I had had a dream that I was picking mushrooms in the forest, I got ill in a day or two. It was like my body was already fighting virus and alarming me that it was about to lose the battle.
I didn't have these dreams for quite a while (which doesn't mean I don't get sick - I do, just don't have a heads up now). But last night I had a very peculiar dream like I was strolling down the beach and collecting shells. The whole mood of the dream was very familiar. I wonder if this is my old friend visiting me under disguise? We'll see. If I get sick in a couple of days - that's it!
