Hello friend and welcome.

It's always nice to hear someone else has joined the ranks of Lucid Dreamers everywhere. I believe you mean to say that you felt elated after the dream. Groggy describes a feeling of not being fully aware yet, still sleepy. However, the important thing is that you know what a Lucid Dream feels like. Stick around here on this website and you will learn many ways to have that experience over and over. Good luck and happy trails.
