I have seen shadow like figures since childhood. I have never been scared of what I have seen. Lately however I seem to allways see a sort of light flash out the corner of my eye. It all way's seem to come from my room. Sometimes even if the door is closed I will see it right on the door . This has been going on for about a year now. However I don't see the shadows as much as I used to. Any ideas as to what this is??
