I think that the problem you maybe experiencing is that you were expecting a lucid dream like the other nights and you were disappointed to find that you woke up out of the dream when you became lucid. I think that this probably took you by surprise because you were not expecting it. I'd imagine you didn't want it to happen again and with these negative thoughts of it happening again maybe triggered it to happen in most your other dreams in which you became lucid. My advice to you is that you don't expect yourself to become lucid, just be happy if you do become lucid, and your probably going through a bit of a bad luck period, i'm sure the next lucid dream you have will be better. It can happen to all of us at times. I hope your next lucid dream is as good as the previous lucids
