What it says on the title. Mine was when I was 12 and I lived in a very haunted house which had some weird activity going on, like things moving out of place and pets freaking out. I was sitting in the computer, alone in the house, and suddenly I see a shadowy figure on the screen, just some meters away behind me, thinking was my mom I turned around and there was nothing, but the room had turned extremely cold suddenly. There was nothing behind me that could have been this shadow.
It… wasn’t scary? I’d need new sheets.
I mean, it wasn’t like I was looking at some horrific ghoul or something. She was pretty. I’m not sure if I witnessed a spirit, so much as possibly a non-gruesome teleporter malfunction.
