Did I experience sleep paralysis last night?

I was laying in bed, trying to fall asleep, but as I was drifting off, I tried to move my body and sleep on my side and I realized I couldn't, then I tried to move my arm and head and realized that I couldn't even move anything. when I knew I couldn't move anything, I felt a ringing in my head and for some reason my instincts told me I was in extreme danger as I couldn't see what's happening in my room. after that I just told myself to stay calm, don't panic and I could move again afterwards. it was like my body fell asleep with my eyes open. ofc I didn't get a wink of sleep after that cause my heart was pounding.

the entire experience happened in 15 seconds, maybe a bit longer. is this what sleep paralysis is like?
