Hey Gordon,
In response to the coincidences....
For as long as I can remember, I could watch a movie, recognize some actor as someone I hadn't seen in a while, then flip channels and see him again, pick up a newspaper and see his picture, or hear his name in a radio... seemingly in "threes"... It could also be weird scenes in a move.

The weirdest, I remember about 20 years ago seeing an old black and white movie where the thief is hiding money in his false leg... then my dad comes home with a "new" Arnold Schwarzenegger movie and in the opening scene, Arnold is ripping the leg off of this guy, turning the leg upside down, and cocaine spills out.... these are the kinda things (like, what are the odds?) that I'm referring to...

I pointed out this "phenomena" to my girlfriend (now wife) about 5 years ago, and we now have fun recognizing these "chance occurances", saying things like,
"that's 1"... or
"ok, that's 2"...and
"there's 3", etc....
sometimes it's several...

I've always tried to find some sort of link or message, but never have that I'm conciously aware of.
There was an Australian book titled something like "Twice Is Coincidence, Three Times Is An Angel", that spoke of how these things can be "signs and messages".... I almost bought it but didn't, now can't find it.

As you mentioned "radio receptors"... maybe these things that we acknowledge are ALWAYS there, and it's just a matter of what you're tuning yourself into and "allowing" yourself to pick up and recieve.... for now, it's just a fun novelty.... something my wife and I don't put a lot of weight into, but get a kick out of it when it happens.... not real infrequent, but so, so, so random.

Not just actors and movies, but numbers, situations, names ( seem to hear a unique name over and over again in a period of a few days)...
Interesting topic!
Thanks Gordon!
