My First and Unintentional Lucid (or Similar) Experience

Last night I had a very weird sleeping experience which kind of scared me at that moment. I'd like to share it with you since I think that my friends or family in the "real world" would probably not understand it. It was around 5:30 am that I went to bed after a long and busy day. My body was screaming for sleep but I had to stay up so late in order to study for an important exam. The sun hadn't still come up by then. So I laid down and closed my eyes and not so long after that I felt myself looking at the windows in my room and making them light up or stay dark simultaneously by wish. I was aware of the whole room and I was in the same position as when lying down so it was extremely realistic. But then it hit me, I remembered reading different articles about lucid dreaming and the act of controlling one's dreams. I felt curious of what I can do in this state which I hadn't ever even tried to experience, so I tried to get out of bed when I had a feeling that as I was getting up I was also starting to detach from my body. This was the point when I got scared and tried to wake myself up. I was awoken but I couldn't move a single muscle of my body. I couldn't even open my eyes fully, I just saw a little of the room from the small opening in the corner of my left eye and panic overwhelmed me. I tried to scream for my mum but I couldn't do even that. Then as I gradually started to regain muscle control I felt my self breathing fast and intensely and I was hearing a loud buzzing sound in my ears as my heart was rushing like crazy, probably because I got so scared. When I opened my eyes completely I looked at the clock and it was 5:45, so it all happened in 15 minutes. I was still tired though, my body was falling asleep again. But I felt that it was going to start all over again so I got up and made myself stay awake some 30 minutes until the sun got up. After I woke up today I felt really stupid for getting all scared and now I'm very sad for missing an amazing opportunity like that. I hope to experience another dream like that in the future and hopefully keeping my calm.
