A strange night, warm and humid. I slept badly, as always. The difference with last night (in the early hours) is that I had a visual hallucination.
It was a figure, in the darkest part of the room, a yard from my head. The figure was an exaggerated one; marching on the spot, monochrome, side-on to me.

It didn’t appear human. Without lifting my head from the pillow I reached out my hand to touch it, a couple of times. Nothing solid, and no reaction. As unusual as this was, I wasn’t afraid and was too sleepy to react further. I turned over, facing the opposite direction, and fell asleep again. Next time I woke in the night there was no figure there.
