What are your thoughts on me still using a nightlight?
Why would you still use a nightlight?
I am afraid of ghosts
Everyone has their own experiences in life and it seems your experiences has led you to fear ghosts. You should confront your fears and not be afraid of the dark. Fears have a tendency to get worse so you should confront this now.
I'm going to.
It's good that you are willing to confront your fears. Using a night light while you work on doing that is fine. You aren't hurting anyone by doing so.
