Over the past few days, the lucid dreams I've been having are quite short and end unexpectedly. It's not like as soon as I become lucid, I run off to do one of my lucid goals. Whenever I become lucid, I try to stabilize the dream, by taking a look at everything and using all five of my senses. For instance, I had a lucid dream last night that ended quickly, without any warning. In the dream, I became lucid, by noticing I had more than five fingers, on my right hand. Like most lucid dreams I've been having lately, the setting has been in my living room. I have been following the same routine, by examining the living room, then I rub my hands together. After that, I usually rub the carpet, or find some other object to feel. That's the most I've been able to do so far in my past few lucids. Does anyone have some advice, to prevent this from happening?
