Dangerous fearful and dark
D) For oft, when on my couch I lie
In vacant or in pensive mood,
They flash upon that inward eye
Which is the bliss of solitude;
And then my heart with pleasure fills
I believe it is the first choice, reading a journal that is unedited and unorganized.
This is because your stream of consciousness is whatever comes to mind, unedited, not necessarily factual nor easy to understand.
I Believe It's D. Dramatic irony
