Welcome to Dreamviews! I've never had that happen to me, but I'm sure you're not the only one who's experienced it. Dreams are funny things.

When you're lucid, it's important to always stay confident, both in yourself as a dreamer and in the dream. You should also keep some focus on your surroundings; it might help prevent the location you're in from shifting around or changing completely.

If you have any other questions, don't hesitate to post, or send me a PM!
