this kind of thing really freaks me out because when i was a kid i would hear stories from my family and relatives and my grandmother would tell me that it's hereditary like if your family has a history of seeing ghosts your family is just closer to the ghost world's door or something to that effect (it's hard to make a direct translation since it's like idioms and ****). and like it wasn't just the older generation like parents aunts and uncles it was stories from my siblings and cousins AT A VERY YOUNG AGE telling me that they were seeing ghosts while i was with them and it was ****ing terrifying. and i swear to ****ing god i have felt ghostly presence in my old room (i had to switch to another room because of fengshui issues) and it would keep me up at night as a child. but this room is so much better, but i'm terrified of a lot of things (like looking in the mirror at night or just the dark in general, window reflections etc)
I had to move rooms in the house I'm currently in as well, I always felt like I was being watched and even to this day it makes me uncomfortable. The day before I started 4th grade I was trying to go to sleep and I opened my eyes to see my closet door opening (and I could hear it), I froze in bed and when I got the courage ran like hell.
