[Pause.] Some nights she wouldhalt, as one frozen by some shudder of the mind, and standstark still till she could move again. But many also were thenights when she paced without pause, up and down, up anddown, before vanishing the way she came. [Pause.] Nosound. [Pause.] None at least to be heard. [Pause.] The sem-blance.
I feel like this one may be a bit of a reach, but I find that the word "frozen" can have a very different meaning. I very much interpret this monologue as May is a ghost recounting old events or memories. In that, I feel like she may be talking about herself and that she is ". . . frozen by some shudder of the mind . . ." Meaning she is stuck in these events/times. I also think that the words vanishing or without pause are something to note.
