Why did the creature haunt him for all his life?

Answer:

It was such a strange and horrible creature
Discussion:
I immediately shut the blind and run out of my room. I was in the hallway when something strange happened. I was running when my eyes rolled up in to my head and all I saw black. The next thing I knew was facedown in my bed.
The main idea of the third paragraph is
The writer saw a creature outside
Discussion:
Anyway, I gathered all of my courage and crept slowly to my window. I held my finger out and raised one of the blinds. I had my eyes closed doing this. I opened my eyes and looked out. My eyes met another pair of eyes. What I saw will haunt me for all 
of my life. It was about 15 feet away from my window. It was a naked dark grey creature about 3 to 4 feet tall.
