Learn English – Good word for something physical that’s inexplicable

synonymsword-choice

I'm looking for a word to describe something physical, something that you can tangibly and empirically feel, but cannot see, nor sense in any other way than touch, nor explain its imperceptibility. Does anyone have any ideas?

EDIT: If anyone can think of a single word for such a definition, that would be fantastic! 🙂
