I-Search topic

For my I-Search paper I want to focus on the mentality of a child. Why are children afraid of the dark? What makes a child fear the dark? I want to do this because it will be interesting to find out why children are so gullible about scary stories about the dark and why they get this way. Everyone has a fear of something but a child's number one fear is the dark. I wonder what they think is in the dark? It's just a place with no lighting. I remember I was afraid of the dark when I was little but I don't remember why. This is why I want to do this topic on my I-Search paper.
