Ahh, you are one of the lucky ones that didn't need to work to achieve lucidity :p good on ya. Haha. And I think you might be referring to the Astral Plane ? It is a wonderful place that many of us wish to go to but do not see very often, I suggest you read up on it as it is very interesting. A place where you are at one with everything, just as everything is at one with you. So much information is readily available and many entities are ready to show themselves to you, you only need to allow yourself to see.
