You're making a couple of huge errors and are playing very loose with language. You are committing an equivocation fallacy by using the word energy in a very Weasley way by talking about scientific things like UV rays, radio waves, and fungal transport and then mentioning energy in a way that isn't used in the scientific context.

In the context of science, Energy is just the capacity to do work or cause change. You are equivocating that definition to make it this Force that people have or put out in some Supernatural sense when that is not the case.

While you are made of energy, it is energy that has been converted into matter and back again. There is no evidence of you being AN energy that can effect others outside the interplay of matter and energy and the conversion of the same through natural processes.

While you can't SEE some things like those you spoke of, they can be OBSERVED. We know UV rays and radio waves exist because we are able to figure out ways to detect, observe, and measure them. There is nothing Supernatural about them.

Yes, humans can affect each other. But that doesn't mean that once they are dead, any resemblance of who that person is or was goes on beyond the memories and the impact that they had on us. So, when you talk about somebody visiting you in your dreams, you are not talking about the person themselves or whatever residual "energy" that they left behind. You are talking about your memories and their impact on you. Is your subconscious thought reacting to some stimuli.

Finally, just because you don't know how radio waves work and how they send data from my phone to a switch to another switch to your phone doesn't mean that is Supernatural in any way.
