If I have a sentence:
There are many stories which have been told about a ghost that haunted this castle. Strangely, ... (the ghost) has never appeared in front of my face for 10 years.
I notice that when it comes to "spirit, dark force", many people use "it" instead of making it personalized by using "she/he" as the subject pronoun.
Should I use the subject pronoun "he/she" or "it" to refer to the ghost?
