My lucid dreams have ended in different ways, but the most common is the world around me falling apart. Here is an example. I was at my beach house with a bunch of dream characters, and I knew that the dream was going to end soon. I went outside and looked into the distance, and actually saw the world collapsing, getting closer. I said goodbye to the dream characters (as I always do ) and watched it get closer. As it got closer I decided to try and stabilize the dream to keep it going longer, so I spun around a couple of times and then looked up again. Although the scene didn't change, the collapsing stopped and the landscape was as if it had never started. I asked the dream characters if they knew how much time I had left, hoping to get a response from my subconscious. I wanted to make sure I didn't start any long process with limited time left. After about a minute or so the world started to collapse again, and as it got to me I woke up.

How do your lucid dreams end? All responses are appreciated!
