I'm not an expert at this, I've been out of practice for months, but I seem to remember a suggestion about doing a reality check whenever something unusual happens, or if you recognize a dream sign from your dreams, do it whenever you see the dream sign in reality. Example: If your dream sign is a cat, when you see a cat, do a RC.

I don't know what would happen if you RC 'each time you go through a door', beyond people wondering about you.
