Sounds pretty realistic. A high level lucid dream. I myself am a noob too but ive read some stuff on Out of body experiences and it could be something of that nature.

When your in a dream and you at some point come to realize "hey, im in a dream" that is the point where you become lucid, like Blargh said, its called a DILD.

And you can experience it again! If you havent already found the tutorial on Lucid dreaming it starts here

Well anyways welcome to DV and have good dreams!
