Lucid Paralysis Experience

Hey, I've known about this site and lucid dreams for awhile but never actually had one, only a few odd dreams here and there.

Anyway, last night I had a dream that really freaked me out, went to bed at 11:30pm and "woke up" with a shock as though I'd been thrown into a pool of cold water, I wasn't really seeing anything but I knew that I could think properly and I tried struggling but couldn't move. I've had a previous experience where I felt like I was moving through space but couldn't move my body and I concentrated and snapped out of it cause it felt horrid, but this time I just went with it.

So there I was feeling like I'd just been thrown into a pool of cold water, just floating / moving in a semi-uncomfortable way, then the next thing I remember is just flying through this liquid, and peoples faces were going past, all different people and it kinda spooked me out, felt like it went on for hours. Here is where I thought to myself the kind of 'holy crap what's going on". Then I remember all these words and symbols flashing infront of my eyes and I was trying to read what they said but it was going too rapidly for me to make them out. The whole time I could not move and in the end didn't even try moving anymore.

Then I remember nothing more, woke up as though nothing odd had happened and just did what I normally do, shower / get ready for work etc. Then on my way to work I remembered this experience and a flood of "wooooah I remember that" washed over me.

Was this a type of lucid dream? Or...? Sleep paralysis kinda stuff, freaks me out... Look forward to seeing what people think.
