Years ago, I went through a time where I had to do work overnight, basically alone (except for security guards at the front of the building) in a darkened, relatively old building. I've never been 'sensitive' to ghosts or the paranormal, but its very easy I guess to let your imagination run wild, to creep yourself out especially if you enjoy watching scary stuff (like I do). But if you're busy and chasing a deadline, you literally have no time to notice creepy things lol.
Could you help out. Pray The Divine Mercy Chaplet, specially for the sick and dying. Read about the extraordinary promises that Jesus Christ gave when it is prayed. This is what you can do. Each. And. Every. Time. Divine Mercy, we trust in you
