The ellipsis after the first line indicates that the next line ("you'll get no sleep") is not a continuation of the above, but rather a separate thought, as though the person started with the normal mindfuck caption but then stopped and said "you'll get no sleep". And how would that face inhibit sleep in any way? That line is meant to mean that you will get no sleep because you are up all night obsessing, searching for the mindfuck that isn't there.
