Hey, Guido. Welcome to DreamViews! And congratulations on your first lucid dream!

Don't worry that you woke up as soon as you became lucid. This happens to most people when they have their first few lucid dreams. They become too excited about finally becoming lucid and wake up. Like Ryman said, you'll get better at stabilizing lucid dreams with experience.

Keeping a dream journal is important. It will increase your dream recall and the vividness of your dreams. Also, having good dream recall increases your chances to become lucid.

If you are new to lucid dreaming, a great way to start is by reading through Sushi's Beginner's Guide to Lucid Dreaming.

If you have any questions at all, feel free to ask.
