A few days ago, I had a horrible dream that scared me. I don't know why, but I woke up in my dream and I found an human head beside me. The head was bandaged and had blood. After seeing the head I saw blood on my right arm. I thought that the head's blood could transmit me a disease. I remember I was looking for a doctor in my dream.
When I woke up I thought "Luckily it was only a dream!".
Has my essay mistakes? Could you correct it, please? Thanks in advance
