I., ll. 12-18:

And, truly, waking dreams were, more or less,
An old and strange affection of the house.
Myself too had weird seizures, Heaven knows what:
On a sudden in the midst of men and day,
And while I walked and talked as heretofore,
I seemed to move among a world of ghosts,
and feel myself the shadow of a dream.

Variant lines from the UCL MS:

And truly I had glamourish waking-dreams
That sometimes held me for an hour or twain
(They were an old affection of our house)
And sudden weird seizures when I seemed
To walk among a world of hollow shows,
And framed a thousand monstrous fantasies,
And felt myself the shadow of a dream.
