The first change we noticed came after a lapse of some minutes.

Her hands began to move slowly, as if she was groping in the dark.

Words dropped one by one from her lips, in a lost, vacant tone, as if she was talking in her sleep.

Whether what she said referred to past or future I cannot tell you.

She spoke of persons in a foreign country--perfect strangers to my sister and to me.
After a little interval, she suddenly became silent.
