My mom had once told me that she had a bad dream where someone grabbed her, and she bit the person's hand and it was like biting through dough. One night, during a dream, I remembered this and bit the area between my thumb and my index finger and there was no feeling.
Also, food has no taste when I am dreaming. It doesn't even really have texture.
The worst part about sleep paralysis is that things happen to you while you are in bed in your room (or where ever you fell asleep) and things seem too real-- ghosts trying to choke you, a monster slowly crawling towards you, or just some person in the mask breaking into your house and you can't move or scream to ask for help.
Sometimes it happens at night and you can move around (but that's a dream), then you wake up and can't move (and that's either sleep paralysis or yet another dream). Then you wake up for real but you don't know if that's still a dream.
Sometimes it happens during the day when you nap. You can hear people around you talking but no one seems to see/feel that building is about to be destroyed or hear you screaming because you can't move your lips.
Luckily, I learned to control it. All you need to do is calm down and say that it is a dream. Personally, there are clues that give up the fact that I am in sleep paralysis-- I can't see faces clearly, regardless of the thing being alive or inanimate (like stuffed toys). So I just calm down, admit that it is a dream, and fall asleep again.
PS: I also wouldn't call it "suffering sleep paralysis". It happened frequently (several times per month) when I was young but after I turned 22 it might have happened 3 or 4 times only.
When I am dreaming I have to check often that I am not actually awake, so I have a trick I use to make sure that I am dreaming. I know, it sounds a lot like Inception.
A little more - I had night terrors up until I was 12. I would walk though my house in a frantic dream state, sometimes seeing things that weren't there on top of things that were. Maybe the lucid dreaming and early night terrors were connected.
