Again Stephen expresses difficulty in trying to figure out the chronology of specific events, but this particular part of the story is unique because he is not sure whether a certain vision of Uncle Peter is a part of his memory or is a potential product of his imagination. Both of them seem equally vivid and real, so much that it is easy to confuse them (though in light of later events, it’s obvious that his memory of Uncle Peter returning home in glory is a false one). As such, Frayn introduces another potential obstacle to the idea of memory as a wholly accurate medium: the disturbance of imagined visions. What is also striking is that imagination can be as detailed and concrete as a memory, or even as present, lived reality.
