which fear is afraid? That in the face of which one has anxiety is not an entity within-the-world. Thus it is essentially incapable of having an involvement. This threatening does not have the character of a definite detrimentality which reaches what is threatened, and which reaches it with definite regard to a special factical potentiality-for-Being. That in the face of which one is anxious is completely indefinite. Not only does this indefiniteness leave factically undecided which entity within-the-world is threatening us, but it also tells us that entities within-the-world are not 'relevant' at all. Nothing which is ready-to-hand or present-at-hand within the world functions as that in the face of which anxiety is anxious. Here the totality of involvements of the ready-to-hand and the present-at-hand discovered within-the-world, is, as such, of no consequence; it collapses into itself; the world has the character of completely lacking significance. In anxiety one does not encounter this thing or that thing which, as something threatening, must have an involvement.
Accordingly, when something threatening brings itself close, anxiety does not 'see' any definite 'here' or 'yonder' from which it comes. That in the face of which one has anxiety is characterized by the fact that what threatens is nowhere. Anxiety 'does not know' what that in the face of which it is anxious is. 'Nowhere', however, does not signify nothing: this is where any region lies, and there too lies any disclosedness of the world for essentially spatial Being-in. Therefore that which threatens cannot bring itself close from a definite direction within what is close by; it is already 'there', and yet nowhere; it is so close that it is oppressive and stifles one's breath, and yet it is nowhere.
In that in the face of which one has anxiety, the 'It is nothing and nowhere' becomes manifest. The obstinacy of the "nothing and nowhere within-the-world" means as a phenomenon that the world as such is that in  the face of which one has anxiety. The utter insignificance which makes itself known in the "nothing and nowhere", does not signify that the world is absent, but tells us that entities within-the-world are of so little importance in themselves that on the basis of this insignificance of what is within-the-world, the world in its worldhood is all that still obtrudes itself.
What oppresses us is not this or that, nor is it the summation of everything present-at-hand; it is rather the possibility of the ready-to-hand in general; that is to say, it is the world itself. When anxiety has subsided, then in our everyday way of talking we are accustomed to say that 'it was really nothing'. And what it was, indeed, does get reached ontically by such a way of talking. Everyday discourse tends towards concerning itself with the ready-to-hand and talking about it. That in the face of which anxiety is anxious is nothing ready-to-hand within-the-world. But this
