Synchronizing wave lengths

I'm going to start this out by saying I'm an open-minded skeptic. I believe there's a possibility for things like shared dreaming to happen... but have never seen a convincing case.

Anyways, I arrived at an interesting conclusion using some logical points I've heard before on the subject.

The brain gives off certain wavelengths of energy. Different frequencies of vibrations can both affect the brain and be given off by the brain. Theoretically, people will share dreams/thoughts being on this same wavelength (or, depending on belief of the "energy body" or similar concept, might still have to resonate similarly).

So, then, if two people are trying to share dreams/thoughts/etc., wouldn't it make sense for people to synchronize these? Now, I don't have nearly enough of a detailed knowledge to know that it would even change the resonance of each person's thought patterns... however, two people who are close to each other may try centering around the same frequency for a while either before or during sleep. For example, they may find a highly resonant crystal and find a manner of striking it, or else both use the same binaural beats. If we accept the things mentioned above, shouldn't this also theoretically increase the chance of sharing things?

Not to say I'm even entirely convinced, I just thought maybe it should be considered.

In my dreams that incorporate other people's thoughts, and vice versa, I'm fairly certain that there is no frequency that selects the other person's thoughts. We know that no scientifically known kinds of vibrations are involved in dream sharing - both sound and electromagnetism are far too weak - so some other supernatural mechanism is involved. Suppose that you could divide the mysterious thought-frequency spectrum into 100 frequency bands, like is done with radio, which is where the 'on the same frequency' metaphor comes from. Then instead of 7 billion people talking at once on the same channel, you could do no better than 70 million people talking at once. I don't see how that can work. Shared lucid dreaming would be different from what I experience, but the same principle would apply.
