Fun day, Crazy dream

so today i had a weird dream, it was a dream of me sleeping in my bed. i was next to my girlfriend and there was noise coming outside of my room. i was thinking to my self, what was that noise? my girlfriend got up and walked outside the door, and whatever it was that i heard outside had now came into my room. i thought i was my little sister, but as it got closer it started getting harder to recognize what it was. it was also mumbling something that i couldnt understand. it was starting to creep me out, i felt my body get goose bumps and i felt my heart rate growing. i then realized that i was in a dream. i felt my body as if i wasnt dreaming, but my mind was still in the dream. as the thing got closer, i couldnt move in my dream. i didnt understand why. so i still remembered that i was dreaming and i knew my girlfriend was next to me as i was sleeping. i remember gathering my strength and trying to reach out to her in the non dreaming world and i was saying betty, betty.. in my dream. i also still couldnt move as the thing was aproaching me. it came almost 1 foot away from me and then my girlfriend woke me up. she said she heard me calling her in her dream.
