Getting to excited.your actually waking up before your about to really dream.You might be trying too hard to catch your lucidness.What I have learn for months now is that luciddreaming is like your body clock that wakes you in the morning.That's why reality checks are important, it helps set the bait as you wait.But as you wait for the big catch just think about a good moment with no expectations.(soon the fish will bite but you must wait a while and have faith that your mind will pull through.)
