Sleep Paralysis?

[gaz14]

Hey guys, just read the Sleep paralysis article in the tutorial section, and think it might have been what I went through last night. I was lying in bed, and then quickly fell into a dream, although I was aware I was dreaming, in the dream I was lying down and could not move and my eyes were stuck in one spot, I tried to speak but could not and I also heard some sort of music playing , this may have lasted for maybe a few minutes and then I woke up and finally turned over and went to sleep. Can anyone tell me if this is what sleep paralysis is? Or have i experienced something different entirely?
