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.
I saw a person materialize over my bed one night. It wasn’t scary or anything, but I was fully awake, and saw a person standing in my room in front of me. She looked like a normal living person, dressed in modern clothing. She looked over towards me, and suddenly vanished into thin air.
I have questioned my sanity ever since.
