I have had similar issues, mine is something hiding in the closet most of the time. It is easy for me to know it is absolutely ridiculous because there are no doors on my closet and it is packed full of stuff. Even still I have to turn the bedroom light on "calm" myself. It's not all the time and I have never thought much about it, just in the moment. I find when I feel irrational it helps to talk myself down, bring reason into perspective. I hope you are feeling better.
