why does this make me feel so uneasy?

...

If my dream last "night" didn't do it, how could this?

...

I was asleep. A man came in my door and came over to hug my sleeping form hello. Then he seemed to be gone, but sometime later there was a great thundering down the hall as he ran from the back bathroom and in here to my bed. He leapt on me giddily, as though he were Alex from A Clockwork Orange, naked, with a stupendous hard on, and without his droogies... grinning at me.

Pleased as punch. Almost what you would call "in love". He's only in his mid-twenties or so. Slender. Very strong. Long straight light brown hair. Happy as a damn clam.

He's all over me and around me, with lots of covers intervening in spots. He's sucking on my fingertips and poking me in the side with that steel dick. I'm reminding him that I'm old. Careful now.

Suddenly he's in my bed and I'm pacing the room. He's asking me what I did in my youth. I started telling him.

He vanished.

Then the suddenness of him disappearing woke me up. The hug and the thundering down the hall and the leaping on me and the finger sucking and the hard on from outer space sounded and felt as though I had not been asleep as they transpired.

I was back in that startled but purposely not letting fear grip me thing.

I mean, I'm darn sure I'm not intimate with anyone of that description.

I think he disappeared when it was completely clear I wasn't afraid.
