I think this experience is more common than just something that happens to me so I’m asking here. Have you ever been sitting at a table (or on the floor or in a car, etc) with a friend and suddenly both of you start singing the same song at the same point with no knowledge that the other person is going to start singing it?
That happens to me sometimes. Depending on the song and the person, it can get very weird. 
When I was in high school, the whole science class busted out in Garth Brooks’ “Low Places.” Hmm… that was kinda creepy.
I’ve done that with my husband on more than one occasion. I think it’s because we’re in “sync” or something (and no, I’m not alluding to the musical group that tries to sing from time to time )
Once I picked up the phone to call my friend, and he was already on the other line! He had called just before I picked up, so I got to it before it rang! Uncanny!
Happens with my wife and me pretty frequently. We even start in the same key! And not always at the beginning of the song.
That’s what I’m talking about. 
Oh dear! This is clearly evidence of demonic possession and none of them seem to realize it!
Theologically dangerous, I would say.
Why are we whispering?
I can see how there may have been some shared experience that prompts the same tune to come to mind for more tham one person.
I have also had it happen where a tune would come to mind and I would mention it to those around me, even though I didn’t know them well, and they all said the same tune was playing in their heads, too. That one was too hard to explain away (we were a group of new employees walking along a sidewalk from work to a bar, and Queen’s “We Are the Champions” was exploding in my head).

(I have possessed him since 1968 and he still hasn’t cottoned on 
).
Posessed me? I wasn’t even born in 1968, you buffoon!
Clearly this is evidence of some kind of pre-existence. DJM, are you a Latter-Day Saint?
Ouch. 
That’s great!
The refernece was to little Lambchops’ joke. There was no reference to you whatsoever. Why do think everything is about you? As to buffoons …
Sorry, I don’t get it. Must be some insiders’ joke for Mormons. Seeing the company you keep, I’m not surprised.

Deej, this nonsmoking is getting the better of you!
Jeez DJ,

Yes, same here.
Thinking of a certain song and someone at work will start singing it.
All of us are psychic, some more than others. We live our lives in a veritable soup of mental fields. Naturally, we pick up what others are thinking, especially if they are close to us, either physically and/or emotionally.We can sometimes sense what others are thinking or feeling as clearly as if they had called us on the cell phone. And this communication can happen if we are separated by thousands of miles, just as long as we are connected in other important ways.
Well, I knew you were going to say that.
No, but I have experienced spontaneous exact face numbness involving a group of people. 
We all decided it must have been caused by an excessive amount of MSG in the Chinese food we were eating. We looked it up in a book and that was a symptom of overdosing.
Hmmm I once always knew what was playing on my radio before I turned it on.
Here’s one for the conspiracy folks:
Get your copy of Cool Edit Pro and make a recording of a noisy street scene - particularly if there’s a lot of aircraft noise. Now use the noise filter to start removing various sounds - don’t specially try to isolate them, just grab a bit into the profile-sample and filter the lot with the profile. After 4 or 5 passes with diferent profiles - can you hear the voices?
Here’s one I’d like to try some day:
Get lots of digital photos of ripply cloud patterns.
Write a program to take grey-scale levels across a line scribed on the photos (like a linear screen-cap) at 90 degrees to the ripple-fronts.
Convert the resulting number strings to a .wav or .au file and listen - I often wonder what clouds sound like and if they have anything to say.
