I was conscious and everything was extremely vivid.  During my lucid dreams, I'm always in control and I'm always on "earth" or a place that looks like earth (except there are always animals that I've never seen before). This experience though, was different.  I became conscious in the midst of the traveling through what appeared to be space, but rather than control it, I just kind of went with it.  I just enjoyed the scenery (stars and darkness) and then wondered, "where the heck am I going to end up?"  It seemed as if I was traveling through a tunnel of stars, really fast.  No sounds, no vibrations.  Just lots of stars and I seemed to be moving pretty fast.  Is this enough detail?

I've had lucid dreams before, but something happened two nights ago that was very strange.  I was going through a tunnel, except it didn't look like a tunnel - it looked like I was in the cosmos.... stars all around me and vast dark-greyness.  And I realized, holy crap, I'm conscious and this is so cool, where am I going??  So I went along with it, til I got to the end and saw an opening with entities/spirits/people??  And they looked like they were made of gas or something and they wanted me to come in to their "place" and I wanted to go, but I couldn't get in there.  (I don't remember what happened after that....so I probably woke up or, well, I'm not sure what happened, but I don't remember anything after that.  I had some lucid dreams that night, but I don't know if they were before or after my little trip into space.) 
So my question is.... was I astral projecting?  What the heck was happening.  It was completely different than having a lucid dream... I was in a totally different place - it didn't look familiar and it didn't look like any of the places I ever visit in my dreams.  Any one have a similar experience?
