Please help. Does this sound like sleep paralysis or me dreaming that I was having sleep paralysis? I’m so scared

I have never ever experienced sleep paralysis before. I have been taking 7.5mg of Mirtazapine for a month now with very minimal side effects. This morning I had woken up around 9am, I was up for about 30 mins before going back to bed. I was having a dream that I was talking to my boyfriend on the phone in a random setting, when suddenly I opened my eyes to my bedroom. I was laying on my right side (the position I fell asleep in). It was hard to keep my eyes open, and I soon realized that I couldn’t get up. No matter how much I tried, I couldn’t move my head, my arms, anything. If I tried really hard, I could make slight movements, but that was it. I could only control my breathing. I then remembered that I was still on a call with my boyfriend from when I fell asleep at 9:30am. I took a deep breath and managed to let out a small sound. He said something very faintly, I couldn’t really hear. So I made the noise over and over again. I was suddenly able to get up, and I turned to my phone and told him how I think I just experienced sleep paralysis. We had a conversation about it, when suddenly I blinked and was back down on my side again, unable to move. I could barely keep my eyes open, my eyelids kept fluttering. I took deep breaths, and with each one, I said “Please. Help. Me” very, very faintly, because I couldn’t manage to say it loud, and my boyfriend said something, but I couldn’t make it out. So, again, I took deep breaths, and said “say. something. loud.” So he did, and I “woke up.” But I sat up, blinked, and I was back down on my side again. This happened over and over. Sat up, blinked, right back on my side again. I finally just stayed down, trying to think of how the hell I’d manage to wake up from this. That’s when (I believe) my alarm went off (i say “I believe” because I can’t remember if I woke up normally, or if i woke up to my alarm, all I remember is turning it off shortly after I woke up). I sat up, dazed and confused, and turned to my phone and called out to my boyfriend. He wasn’t there. He must be off doing something. It made me question if he was ever even there to begin with, or if I was simply having a dream ABOUT having sleep paralysis, or if I was still asleep and STILL dreaming?

I’m extremely tired. My eyes keep closing and I keep having mini dreams for the 15 seconds they’re closed.

The only thing that has changed is the fact that I accidentally missed a dose two nights ago, and last night ALMOST missed a dose again. I usually take it at 10:30-11:30, but last night I took it around 2am because I had accidentally fell asleep and woke up then. I have no idea what happened. My eyes are so heavy now and I just want to sleep again, despite getting close to 14 hours of sleep.
