Nobody ever mentions the 99.9999% of occurrences where this doesn't happen. It's like the way when someone phones or whatever and the recepient might go 'I was just thinking about you' - the other hundreds to thousands of times they don't, nothing happens.

The idea may be interesting, but it ieeds to be properly testable rather than just based on subjective experience.

I do think this as well. Otherwise it would be quite easy to be mystical.

This is why she does research, to see if it is testable, reproducable, if there if a way to prove this beyond doubt. That is how all kinds of things were discovered. It was assumed that people could not survive in a train carriage if it went faster than 30 or so mph, because all air would be squeezed from it taluna the pressure. It was not until someone proved that it is safe that this notion changed.
Just because something is not proven, it does not mean it does not exist.
James Randi's wants to pay you $1m if you can show him anything like that. People have tried, and none fo them have convinced him.  8)

Well back on topic. I read that tress also use hormones through the air to communicate with other trees and animals.

So if one tree is being eaten by caterpillars, it sends out hormones to let the other trees know and they start protecting them selves against that kind of caterpillars. And the tree also sends out hormones to attract a specific type of wasp depending on the type of caterpillar attacking it.

Not all trees have this capacity however. In Canada, whole group of trees can be attacked by some kind or larva and whole group of trees can become weak and transmit their sickness without being able to defend themselves.

That's the pine beetle you're talking about, and the reason that they can't defend themeslves against it is that it's an invasive non-native species.  The trees don't have any naturally evolved defenses against it.  It's like when you bring a wolf (for example) to an island that has never had wolves.  The prey items, unable to defend themselves against the new threat, will be quickly wiped out.

Thank you for reminding me this (my memories about this date from February 2010, when I went in the Appalachians).  :)
