In that state I slept, in that state also I dreamt, and dreamt horribly. I thought that I was dancing a waltz with an enormously tall woman. She towered above me, clasping me in her arms, and began to whirl me round and round at a giddy speed. I could hear the crashing music of a distant band. Faster and faster, round and round some great empty hall was I whirled. I knew that I was losing my senses, and screamed to her to stop and let me go. Suddenly there was a terrible crash close to me. Good God! I found myself awake, but--I was still moving. Where was I? Where was I going? I leapt up on the bed, only to reel and fall heavily backwards upon the floor. What was the matter? Why was I sliding, sliding? Had I suddenly gone mad, or was I still suffering from some hideous nightmare? I tried to move, to stagger to my feet. Then by slow degrees my senses began to return, and I knew where I was. I was in the circular room, the room where Wentworth had died; but what was happening to me I could not divine. I only knew that I was being whirled round and round at a velocity that was every moment increasing. By the moonlight that struggled in through the window I saw that the floor and the bed upon it was revolving, but the table was lying on its side, and its fall must have awakened me. I could not see any other furniture in the room. By what mysterious manner had it been removed? Making a great effort, I crawled to the centre of this awful chamber, and, seizing the foot of the bed, struggled to my feet. Here I knew there would be less motion, and I could just manage to see the outline of the door. I had taken the precaution to slip the revolver into my pocket, and I still felt that if human agency appeared, I had a chance of selling my life dearly; but surely the horror I was passing through was invented by no living man! As the floor of the room revolved in the direction of the door I made a dash for it, but was carried swiftly past, and again fell heavily. When I came round again I made a frantic effort to cling to one of the steps, but in vain; the head of the bedstead caught me as it flew round, and tore my arms away. In another moment I believe I should have gone raving mad with terror. My head felt as if it would burst; I found it impossible to think consecutively. The only idea which really possessed me was a mad wish to escape from this hideous place. I struggled to the bedstead, and dragging the legs from their sockets, pulled it into the middle of the room away from the wall. With this out of the way, I managed at last to reach the door in safety. [Illustration: "I flung myself upon him." A Master of Mysteries.--Page 47]
