Horror?

A dream story. A little while ago, I was trapped in what seemed like a strange child's room in a dream. Even when I went out into the hallway, I'd end up back in that child's room? Suddenly I thought, 'Ah, this isn't real, it's a dream!' and I scrolled on my smartphone, which I was somehow holding tightly. Even when I stopped my finger, the screen inexplicably started moving on its own with black swirls, and I thought, 'Oh no, this is bad.' The moment I tried to let go of the phone, I suddenly thought I woke up from the dream. Then, thinking I had woken up, I couldn't move. For some reason, in complete darkness, I was holding something like a smartphone in my hand, but I couldn't move anything. There was no one by my pillow, it really felt like I was in some room. But it was strangely quiet, and I felt like there was nothing around me. ...So, I squeezed my eyes shut, and that was also a dream. The punchline is, for a while afterward, the sensation in my hands didn't return. My eyes were open, but even though there should have been nothing in my hand, I felt like I was holding that smartphone from before. For about 2 minutes, I tried to open or grip the smartphone that wasn't there. Even though there was nothing.
