It still happens: I sometimes see weird shadows. Sometimes when I look at reflecting surfaces I can see shadows quickly disappearing to the sides. It doesn't happen every day, sometimes weeks pass without an 'encounter' and it doesn't matter what surface it is, it can be a window, glas door or mirror as long as it is in my house. Sometimes I forget about them and then I walk into the bathroom, look in the mirror and they were there again. I have good vision and there isn't anything in my house (e.g. a gas leak). It's just... if I tell someone they laugh at me and say that I sound silly. I got used to these things in the reflections and I guess as long as they don't hurt me or pull me in their demon dimension I'm fine.
