It means you need to change your alarm clock from air raid siren to the sound of a dog barking. :P
Really though, you should keep a notepad by your bed. Write down the dream's details and look for differences each time.

BTW, if you are blessed/cursed with Deja Vu, you might have only had the dream a few times and just think you've had it tons of times. I had this with tornado dreams for a while, but I didn't trust my dream memory so I started a note on my iPhone and wrote down a tick mark for each dream.
