Sleep event

So a weird incident I would say this dream was, I get to class where everyone was questioning if there was homework was do, and everyone was freaking out. I remember specifically going by my buddy <PERSON> and him being all stressed about it. Then saw my other buddy say "Well.. I did not do it..". Fast forward a bit and I am in my room before bed and apparently our teacher did not have time for our class anymore, so we started having class on the phone, 1-on-1 and it was kind of strange but whatever. I was then lying there on my bed looking at my phone when it made strange noises and this sound scared me into lucidity. The phone showed a black screen that was locked and required me to pay money to open it back up, It made this weird sound (((4))) times. I then felt myself semi-lucid and so I laid there with my eyes clothes and thought "I am losing lucidity, I need to scare myself more", So I imagined <PERSON> running around the top floor of my house outside my room It was really quiet in the dream at this point, his foot stomps sounded like fucking earthquakes, this truly scared the living hell out of me. It sounded like he was going to run in and body slam me to death. After a while, I wanted him to run away because I felt ready to get up, so I did and he ran away. I stabilized by looking at my hands and rubbing my face on my hands, I then walk out into the hallway and made out with the wall for more stabilization I then walked out and since it was so dark in this dream I imagined a scene and made the mistake of closing my eyes to change it and woke up Here is the cool/weird/scary part... I checked my phone and I was texted (((4))) times, very recently ... the even more weird part, it was the same friend from my other entry on <PERSON>
