Urgent question PLEASE LOOK. Sleeping problem?

I just got out of bed. When I got in bed, I felt unusually comfortable. I noticed that there was something different about my breathing. It felt heavy. I cant really explain the feeling because I was halfway asleep. Then suddenly, I feel something really wierd. My extremities starting to feel tingly (like when your leg is asleep). It is mostly my legs and I still feel blood rushing from my legs. During this, I tried very hard to move my body to get up but I couldnt. For like five seconds, I had no control. I remember trying to yell for help but my mouth didnt move and no sound came from my mouth but in my mind, sound did come out. The most I got to yelling was my lips touching and a slight groan. And then as soon as it started, it was over. I felt the tingling go away in my legs and I got up to type this right now. I have no idea what just happened to me. It has never happened before and I feel like this is not a minor event. I will apriciate any help at all like refering me to a website.
