No one can tell you what it is. If you ask a doctor, they will say its a physical anomaly. If you ask a meditator, they'll say its a meditation thing. If you ask a psychic, they'll say its spirit contact of some sort. Ask an Indian guru, and he'll tell you it's shiva, lol.

But if it can be used for some personal benefit, it's worth exploring. If it helps you focus, concentrate or shift energy, then it wouldn't matter if its a physical or non-physical cause.

Perhaps if you are able to use this to enhance telekinetic skills, you can come back and teach us? :)

The other thing, you might be highly sensitive to emf, elf or ambient energy. They've linked ear ringing to elf. And I've personally experienced the link myself.
