Form of solipsism

Egocentric presentism is a form of solipsism introduced by Caspar Hare in which other persons can be conscious, but their experiences are simply not present.^[1][2]

Similarly, in related work, Hare argues for a theory of perspectival realism in which other perspectives do exist, but the present perspective has a defining intrinsic property.^[3]

In one example that Hare uses to illustrate his theory (starting on page 354 of the official version of his paper),^[1] you learn that you are one of two people, named A and B, who have just been in a train crash; and that A is about to have incredibly painful surgery.

You cannot remember your name. According to Hare, naturally, you hope to be B. The point of the example is that you know everything relevant that there is to know about the objective world; all that is missing is your position in it, that is, whose experiences are present, A's or B's.
