You should work on your recall first. Also once an hour is a good time to start reality checking. You should also reality check when you notice something strange or dream-like. The nose-pinch reality check is one of the most common reality checks used. It is also one of the best. All you do is pinch your nose and try to breath through it. If you can, you're dreaming! While you are doing the reality check actually believe you can breath though your nose. If you just assume you can, you might not in a dream!

While you do a reality check you should look around you and be aware of everything. Ask how you got there. Don't just make it a habit you don't even think about while doing it.
