Is this sleep paralysis? If so, how do I get to a lucid dream from this?

Hello. I was wondering if any of you could tell me if this was sleep paralysis: I lie in my bed, and listen to some white noise. I lie in bed and relax. I have many urges to swallow, and so I do. Slowly but surely (in about 40 minutes), I find that my body is very heavy. (This was during an afternoon nap after getting 7 hours of sleep, going to school, and coming back home). With this heavy feeling, my eyelids are black. I continue counting to 100 and back down. I'm not sure what to do, because half the time I feel too aware of the physical world, and the other half I feel like I am starting to fall asleep normally, because I lose track of my counting. Sometimes I find a perfect middle, but it last for about 4 seconds before I need to swallow again. I believe this heaviness is sleep paralysis, although there aren't any lights, sounds, or creepy shadows. Is this sleep paralysis? If so, how do I get to a lucid dream from here? I literally don't see anything, except very few dull flashes of light. Help? EDIT: I also forgot to mention that eventually I got fed up with my family tromping around the house, so I got up. I felt very heavy and a bit dizzy for a while, almost like I was in a heavy metal diving suit, but it eventually went away.
