Maybe, maybe not. Do you usually wake up at 6:00? Sometimes it's hard to dream after usual wake time.

Darkness will end my lucid dreams many times. Try turning on a light! Easier said than done. Dreams can fade fast.

Here's a suggestion: Don't think about waking up, don't fear waking up. Banish these thought from your mind. If you think "please don't wake up," your brain will register "wake up," "please," and then "don't." Of course, by then the waking sequence will already happen. Instead, focus your entire thought on your surroundings and dream. The best success is achieved when you remember what has happened in your dream until that point. It tends to keep the mind active on it, and even if you end up waking up, you will be rewarded with strong dream recall (as opposed to only remembering "aw crap! The dream is ending!").
