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.
There’s this theory of a bicameral mind. Where a persons mind can have two separate entities. One is taking care of moving the body, eating, seeing etc. While the other is in the background thinking, giving advice etc. Some say it’s another soul or god. I tend to think it’s more of a survival mechanism that gets rarely used in the modern world. I think it’s related to the third man phenomena.
