Do you ever wake up feeling like you can't remember what's going on or why you're scared?

So I'm 25 and I've struggled with anxiety and depression since I was a teen. I've had some suicidal thoughts but never made a plan, and I've never attempted suicide. I do think about it from time to time, but I'm in therapy and I've made friends that care about me and that helps a lot. I've always been able to sleep with my phone, I would put it next to me and leave it on. But now I wake up feeling like I don't know what's going on, why I'm so scared. It's really weird and I think it might be something more than anxiety. What is this feeling? I'm really scared right now.
