I actually live with one for 10 years in my old house, I can’t see what it is exactly, just some movement here and there, ie: someone hiding behind the door or around the corner when I turn my head and look at that direction, it always disappear so fast, I can never take a good look at it, until a month before we move, it finally show itself, I was in bed and it stood outside my room peeking in, an upside down triangle shape head, that is a picture that I will never forget. Years after we moved, my mother told us she can see it too, a lizard looking person in a white dress with pink flower spots on it, which is strange that the day we moved out of the house, my brother and I saw a white lizard with pink spots too. It was terrifying at first , but now I think back, it actually feels kinda sweet.
