I was thinking about my ocd problem if the thoughts that happened without my will days ago, became valid or not. both times I thought about it, I got a random thought like "what if I hear a door sound now that I made this question to myself? it will be a coincidence" this is what I thought the first time. and the door sound happened. it was someone opening or unlocking his/her door apartment or the door of the main building. but the second time, I got a similar thought and the door sound happened again. I used to worry in the past about the door coincidences. is this a sign or not?
