Sounds like a great first time LD . Now that you know what its like, it will be much easier to lucid in the future! I used to have plenty of LDs many years back, but I kinda forgot about it due to lack of interest and proper methods. I strongly suggest you spend some time on this forum, it has helped me ALOT. I thought I was the only person on earth having sleep paralysis and lucid dreams until i discovered this website. Just being aware of the phenomena let alone might bring you on the right track, as it did for me. Personally I recommand using your hands for reality check. Last night I checked my hands discovering they were half transparent and containing stars, planets and galaxies, which usually don't happen when I'm awake.
Good luck!
