Hallo SiriusTraveler
You probably did have an OBE at some point during that experience. It likely began with a normal dream and gradually your consciousness shifted into astral awareness meaning that as you become more alert and aware it became an OBE. This has happened to me Many times. What started out as a dream became an OBE (or AP) for a short time and then, as consciousness faded, the experience reentered the dream phase again. Sometimes OBEs and dreams can overlap one another. This is a type of dual experience where a person is in both a dream state and an OBE simultaneously. This may have occurred during some point in your experience.

Hope this helps
