You say you're doing a reality check every hour. Do you have an alarm set to go off every hour to remind you? If so, the problem could be that you're not hearing the alarm in your dreams. It's more reliable to set certain cues. If you've identified any dream signs, keep an eye out for those to remind you to RC (e.g., if you often dream about cats, do an RC every time you see a cat). If not, just choose one or two (or more) common triggers to remind you to RC, such as sitting down or opening a door. You should also do an RC whenever the thought comes to mind. Oh, and whenever something seems strange, even if it's just a little odd.
