Hello GreyWarden: I noticed this is your first post here on PC.. So I thought I would welcome you to PsychCentral.

I hope you find the time you spend here to be of benefit.
Personally I don't think you have anything to be concerned about here.

We all have these sorts of thoughts from time-to-time I believe. At least I certainly have.

They're just thoughts. You mentioned you have anxiety & OCD though. The experience you describe is clearly troublesome to you. So perhaps this is something you might want to talk through with a therapist if that is a possibility for you. While the thought you describe itself is of no real consequence, the confusion & anxiety you're experiencing may be. So if you find yourself continuing to ruminate over this experience, you may want to consider seeking some help with resolving how you feel.
PsychCentral is a great place to get information as well as support for mental health issues. There are many knowledgeable & caring members here. The more you post, & reply to other members’ posts, the more a part of the community you will become. Plus there are social groups you can join & chat rooms where you’ll be able to connect with other PC members in real time (once your first 5 posts have been reviewed & approved.) Lots of great stuff! So please keep posting!
