Welcome to the forum, Lizzahy! 
What you are experiencing are False Awakenings or just FAs. There’s a BIG FA-related topic in the Quest for lucidity forum, you should take a look at it.
What you could do is try to reality check every time you wake up, so if you have a False Awakening, you’ll do an RC and find out you are dreaming, and thus get lucid again. 
Good luck and sweet dreams!
Oh, and remember to introduce yourself in the Gathering forum, it will be nice to give you a proper welcome there!
