Okay, I had found a potential problem with practicing LDs.

After a whole night spent trying to have an LD and failing, I tried a last ditch effort to have one. To my surprise, I slipped into one. In my dream, I was lying in my bed as I had been when I fell asleep. I got up and immediately, I heard a low buzzing and I noticed how hard it was to move. If that weren't enough to tell me I was dreaming, one of my friends was in my room, speaking gibberish and flailing her arms around. Of course, now knowing that I was dreaming, I wasn't scared. Instead, I was really excited that I was fully aware in a LD. My thoughts went something like, "YES! YES! FINALLY! I'M IN A LUCID DREAM! HELL YEAH!"

Unfortunately, I got so excited, I woke up. Any ways to prevent myself from blasting myself out of a lucid dream with excitement?
