Weird scary dreams

The past few days I have been having the same dream where I'm in a subway station running away. A distorted figure running close behind me. Lights flickering, floor dirty with broken tiles, dark abyss where the train tracks should be, and always empty. It always starts with me getting off the train, I step out, look around, and there's no one there. The train leaves and I feel a spine chilling breeze as everything starts to dim. Then I hear something, its loud and screechy, when I look behind me I can never get a clear glance at what it is, but I always run. And hear it.. right behind me. I run and run but its different every time. Once I slipped on a broken tile, then tried to hide in a bathroom, I tried fighting back but fell on my head. The worst was when I almost made it out, I saw the sunlit stairs, the exit of the station. Before I knew it I was falling, the abyss of the tracks consuming my body, and when I looked above I saw someone. I didn't know who it was. I didn't want to know. Then I wake up, cold sweat all over, breathing heavy and crying. Last night was different, I was running as I usually do, but I didn't stop, not to look around, not to take a breath, not for anything. I ran for everything I had, I reached the stairs and practically flew to the top, slid under the bars like some game and kept running. I finally stopped at a field, fell on my back into a patch of grass and leaves, and cried. It felt like I had laid there for hours, something different from normal dreams, so real, like I could feel the sun on my face, and the grass between my fingers. I sat up after forever and saw someone in the distance, I didn't want to get up, so she came to me. Asking what was wrong, and I told her everything. About the train, where I was trying to go, even things that weren't relevant. She listened anyways, I told her I was stressed, hurt, and hopeless. She didn't need to say anything, but did anyways. That everything was okay, she was there, just letting me cry into her shoulder, as she stroked my hair and back. I felt safe, after a long time. I felt home. Without anymore running to worry about, I felt free. For once I didn't want it to end, the dream. But it did, now I'm here, wondering if I have to do it all again when I go back to sleep.
