Sleeping

※This story is a fiction.I make sentence for my English study.

When I was 3 years old I had difficulty in hearing.
I had an operation and it was a success.
So I can hearing now.

I got surgery under full anesthesia.
The doctor said to me You will be sleepy.
The next moment I was on a bed.
I woke because I was crying loudly.
My pillow was bleeding. There was blood on my pillow. (Or 'I was bleeding on my pillow')
I remember only this.
It was a very scary experience.
I sometimes can not sleep well even now.
