I recently had a semi lucid dream like this but mine was much weirder. I was at a party (in my dream) and after walking around a little bit i fell asleep on the couch. Within my second dream i was just falling without being able to stop. When i realized i was dreaming i would spin around and be able to stop at a different layer. In this deeper layer i saw one of my friends who is a girl and attempted to makeout with her. Once i did this she shook her head, pulled out a gun, and shot me. Then i woke up but was at the party from my original dream. After that i again tried to hook up with a girl but instantly woke up. It was pretty crazy
