Nightmare

I recovered of a bad cold today. I haven't caught a cold once in the last six months. But I was ill in bed all day yesterday. To be exact, I cannot remember when I last had a cold.
When I looked my report of absence, I couldn't find words of absence from ill. I was surprised. Why? Actually, I didn't have much time to have a cold. I was really busy.

When I have a fever, I'm always troubled by same nightmare. It is like a jigsaw puzzle
Its small pieces are black and white. I become one of small pieces and I am fitted into place. I'm always a black one. And I don't know why, but the puzzle trembles. The nightmare isn't three-dimensional but two-dimensional. I cannot get away from the place where I am fitted and have to tremble eternally… It's terrible sight, isn't it?
Fortunately, I didn't have this nightmare last night. It proved that the fever was not so high. If I look the jigsaw puzzle, I am in serious condition.　

I saw another nightmare last Saturday. I joined a parade of monsters. They were cute, funny and brave. Because I had been to the party last year, I was not surprised this time. Probably as I get used to the party, it will become more difficult to have a shock. Crazy costume competition is right path in Halloween. But I want to go another way next time. I will take a memo about it for next year.
A disguise people cannot understand and will be worried about he/her and cannot decide whether to laugh or not.

What is your costume?
Honey. Am I sweet?

Who are you?
I'm jealousy. Was melancholy much better match for me than it ?

What is your disguise?
A yawn.

I don't know what costume are suit for them. But I have enough time to think about it.
