As others have written getting a trigger you regularly practise is key. Some triggers I have used are:
Watches misbehave in dreams, look at it twice to sus it out. Usually the time changes between peeks.
Light switches. They seem to never work in dreams.
Pushing your hand through your chest. This trigger is very easy and quick. Put your fingers to your chest and push against your ribs without look down at your hand. If dreaming the hand will go through without any effort.
Generally our dreaming brains don't seem to deal well with permanence. The trick is to make it a habit to check if you are dreaming regularly, and at some point you'll do it instinctually in a dream and realize that its not reality.
