This is sleep paralysis? You just described my most hated kind of nightmare (including the try for wiggles, screaming and the hope someone wakes me please up).
It’s so weird. Though I KNOW I’m sleeping, I’m so terrified.
Edit: Sometimes when this happens I “wake up” only to realize I’m still sleeping and in my hated dream. Sometimes I’m several layers inside the dream (fake waking up for 1-3 times), before I finally wake up for real.
Wait, what?
