Have you ever woke up but could not move your body?

Oh my god thank you for posting this! This happened to me this morning and it has me freaked out. I got up to use the restroom and as I got out of bed I just collapsed on the floor. I was confused and decided to stand up and again I ended up on the floor. My left leg was completely gone; I had lost control over it. I started dragging my self across my room and realized my leg felt weird if I held it at a 90 degree angle. I do not know if it was the change in blood circulation or some sort of panic attack but I quickly felt like throwing up and almost passed out. In fact, I would have if my boyfriend would not have helped me. I started seeing black/hazy and some light patches. My boyfriend got me some water to drink, placed a wet cloth on my face/forehead, and tried his best to keep me calm. After some time, I started to feel better and started being able to see again. It freaked me out and I have searched on the internet and it appears you are the only one that mentioned this happening to them. Also the waking up and not being able to talk/move/breathe well happened to me once before. I am now 21 but when I was in middle school (so 12 or 13) I remember waking up and being completely paralyzed. I wanted to get up or scream and I could not. Finally after some time I came out of it and got up. I have also had episodes where I wake up because I had like stopped breathing. However, I simply thought it had to do with my asthma.
