1) In the Gym: I hear the phrase "3 Musketeers" on TV, and hear it said in my cassette novel simultaneously.
2) A character in the novel I'm reading defines "white slavery" at the same moment a news story comes on TV about the Sultan of Brunei bringing in beauty queens for sex.
3) On a hike I'm looking into the clear sky thinking "It doesn't matter that we don't worship the Norse gods any longer..." And I hear one single clap of thunder.
4) In the book-on-tape I'm listening to, the phrase "a thin black cat stretches its leg up" and my own black cat calls to me.
5) I'm removing the clothing from the dryer...my book-on-tape says "What about the laundry?"
6) I was wondering what sort of stone "iceland spar" was. Two days later I hear it described on a television science program.
7) I hear a reference to "mag lev" on a sci-fi tape, and think "What's that?" The next day in the paper there's a kids' experiment explaining the principles of "mag lev."
8) In the bookstore I'm looking at a customer & think "She looks like Reba MacEntyre." Another customer comments in my hearing "The author's name is MacKensie."
9) In my rune studies I come across a plant called the "guilder rose" and skip over it...The next day I'm cleaning up in the "Games" area of the bookstore and come across an out-of-place book on the origins of words. The book opens at random to "guilder rose."
10) I hear the word "elephant" on the radio as I dust an elephant carving.
11) I hear a reference to a Georgia O'Keefe painting of a "pansy that looked like velvet" and look up and see the print of that painting in front of me.
12) As I drive by Helm of Sun Valley I hear the store's commercial on the car radio.
13) I am listening to an NPR interview on the car radio, and suddenly the speaker makes an "aside" about the OJ Simpson trial. I see a sign in a field : "Kato Development Company."
14) I think..."If only I could remember the names of those two outstanding artists I saw in a magazine 10 years ago!" Suddenly a new book comes out about one (Henry Darger) and a search for "outsider artists" yields the name of the other (Achilles Rizzoli.)
15) I think: "How I loved hearing 'that song' years ago. Yet I'll probably never hear it again or know who sang it..." The next day I hear a rerun of the NPR program "Fresh Air" with the very song (Jobim's "The Waters of March") sung by Suzanne McCorkle.
16) (Appropo of nothing, so not really synchronicity, but interesting all the same...) All week I read articles about a mass-murderer being paroled in Santa Clara, and I see the man himself while driving through the Mervyn's parking lot. (A person unmistakable in appearance.) He saw me, and he saw that I recognized him, too.
17) (Yet another, and only "Two Degrees of Separation") My auto mechanic, John, took chemistry under Ted Kasczinski at Stanford.
18) For years I knew a Chinese American man who ran a gift shop in San Francisco. Once he asked me where I was from, and we had both been born in the same small town in Ohio.
19) My father related a story from WWII only one time, in which he vividly described a statue he had seen in the library a Wehrmacht officer's deserted house. While looking for a wastebasket in a room of a home I rarely visit, I come upon a small version of that same statue ("An Old Student".) I know nothing more about it, as the man who owned it could tell me nothing, and a websearch turned up nothing.
20) One day I put a terribly bitter cucumber into the salad, and we were all wondering why it tasted so bad. The very next day I read in the gardening column in the paper about the causes of bitterness in cucumbers.
21) I was standing in line in the supermarket idly scratching my hand & the clerk told me that I "could expect to get some money." I said that I had never heard that superstition...but an Indian man further back in the line said he had. Two days later I read about that belief in The Death of Vishnu.
