As others have said, looking at your hands will help.

This is because it's a way of engaging the senses of your dream body, immersing yourself more into the dream while simultaneously increasing your awareness. Other ways of doing this are to focus on your senses such as smell or touch. Just take in all the data you can about your environment and you will believe more and more how real it is, and that should extend your dreams.

Good luck in stabilization!
