"I must take this other powder," said I. "This is getting impossible."

I tried the wrong side of the hall for my candle and the matches, and had
a doubt of which landing my room might be on. "I'm drunk," I said, "that's
certain," and blundered needlessly on the staircase to sustain the
proposition.

At the first glance my room seemed unfamiliar. "What rot!" I said, and
stared about me. I seemed to bring myself back by the effort, and the odd
phantasmal quality passed into the concrete familiar. There was the old
glass still, with my notes on the albumens stuck in the corner of the
frame, my old everyday suit of clothes pitched about the floor. And yet it
was not so real after all. I felt an idiotic persuasion trying to creep
into my mind, as it were, that I was in a railway carriage in a train just
stopping, that I was peering out of the window at some unknown station. I
gripped the bed-rail firmly to reassure myself. "It's clairvoyance,
perhaps," I said. "I must write to the Psychical Research Society."

I put the rouleau on my dressing-table, sat on my bed, and began to take
off my boots. It was as if the picture of my present sensations was
painted over some other picture that was trying to show through. "Curse
it!" said I; "my wits are going, or am I in two places at once?"
Half-undressed, I tossed the powder into a glass and drank it off. It
effervesced, and became a fluorescent amber colour. Before I was in bed
my mind was already tranquillised. I felt the pillow at my cheek, and
thereupon I must have fallen asleep.
