These thoughts are not about something you’re worried might happen in the future, but rather about things that are happening right now. For example, if you have an obsessive thought about forgetting to lock the door before leaving home, it’s not that you’re worrying about what would happen if someone broke into your house because it may be unlocked; it’s more like you keep thinking about whether or not you actually did lock the door before leaving and doubting that you even did it.
