Well, congratulations on getting that Lucid Dream, Grey.

As for getting one on the fist night, I think it happens to a few people. I've mainly heard that people get them without trying on the first night, maybe another on the second, then it gets a bit harder.

If you do reality checks and keep a journal and everything, it'll be a push towards making it easier for you, because you've had one and you know what you are trying to achieve.
