There is no distinction: the idea that there is a distinction rests on a linguistic confusion. The sentence "something it is like to be a bat" tries, as it were, to split the concept of "being a bat" in two, then makes us wonder about the difference between the two halves. I reject that we have to answer for any such difference, when we can show that the two halves are actually the same thing. It's a grammatical trick caused by collapsing a word that usually relates two distinct things ("A is like B") onto a singular "something".
