It is common to have many false awakenings in a row. And it's also common to slip into a LD afterward. I'm not sure if it's common to get that many LDs but I suppose it's entirely possible.

Real world spacial perceptions in dreams vary from dream to dream, for me anyway. Just try reassert that you are in control, it's your dream and try to overcome whatever barrier is set before you. BUT don't persist for too long or, like me, you'll waste most of a LD beating on a damned wall trying to get through it. Instead of wasting the dream think of something fun you've always wanted to do and go do it.

Good luck.
