Was this a seizure?

Hi, 25, F. It was during the night and I was in the bed with my toddler. It felt like I suddenly woke up, but my eyes were still closed. I couldn’t move my arms or legs or whole body for that matter. But it did feel like I was shaking. I could tell that my teeth kept shutting down but my tongue was flat in my mouth so I didn’t actually bite it. I can’t really tell how long it lasted. But I did finally “wake up” and I thought “ did I just have a seizure? “ but then I went right back to sleep. I’m not sure if it was a form of sleep paralysis, I guess that’s what it seems more like because It felt like I was just laying still but shaking. I just wanted a few opinions. There’s no bruising or anything that really points to a seizure.

Thanks in advance to anyone that responds.
