Weak Sleep Paralysis, or Something Else?

[spellbee2]

So usually when I take a nap, I try to do a full sleep cycle (90 minutes). Sometimes, I automatically wake up after 15 or 20 minutes, but then I just go back to sleep. Lately though, I've had this sensation when I prematurely wake up where my limbs (usually my legs) feel like they aren't there, like the nerve endings are not active or something. I can't feel my bed, my blankets, my clothes. At times it just feels like my legs are just floating. The other day, though, it was my whole body. I woke up, but I didn't open my eyes. I could hear stuff going on around me, like a lawnmower outside, the TV downstairs, etc., so I was awake, but my entire body felt like I was floating. It felt really cool, so I just let it happen. I laid there for about 5 minutes, but couldn't go back to sleep. I opened my eyes, but didn't move other than that. I hesitate to call it sleep paralysis though, since there was no other hypnagogia with it. Plus, it was incredibly easy to break. Moving a limb took the normal amount of effort, and then all the feeling was restored to it. So does anyone have any clue as to what it is, if it is more than just weak sleep paralysis?

It seems like sleep paralysis to me. I don't have much experience with it, but I doubt that sleep paralysis is always accompanied by hypnagogia or other sensations that people report. There could be varying degrees of phenomenon and intensity, since sometimes I will be half awake and unable to move my body, but with some effort I'm able to fully awake. And once I had a weird experience where I "woke up" but with my body asleep (but the lights were on?) and some kind of formless thing was thrashing at my body right above me. It was in my old dorm room, and that was weird. Or again I'll have things were I'll be waking up from a dream or waking myself out of one if its scary, and there will be a moment or two (with eyes closed) where I can't move my body. And the floating part definitely sounds like sleep paralysis too or some kind of out of body experience. But I've never had the hypnagogia, other beings, or scary voices talking to me that people sometimes report during sleep paralysis. Although like I said I don't really get sleep paralysis. It always feels like some kind of false awakening where I can't move my body, and then I'll be awake moments later.
