Dream About School And Injuries

I find myself in a college setting and what's most peculiar is Isaiah is in the same grade as me or at the same school rather. I'm unsure of what class he is taking, or what subject or major he's in, but he brings home a project and it seems pretty cool, has something to do with like math, and they're creating these crystal structures, like clear quartz, but they're trying to make them into like these pristine shapes. At one point, I'm confused as to which grade I am in. At first, I think it's the beginning of my junior year, but then I realized that it's actually my senior year, and then later on I realized that bitch already graduated. The scene shifts and I find myself in a large dining hall, very crowded, and the lights are low, everyone's eating and chatting, and I'm looking around, almost absentmindedly, and this girl looks at me and she's like, oh, hi handsome, and I just think to myself, hey girl, I don't want you, because I just realized that she's being flirtatious, and I just continue to look around after that encounter. The scene changes again, and for whatever reason, Isaiah has changed schools, and I'm not sure where he went to, but he wasn't enjoying his classes. And the scene changes again, and I find myself in another classroom later in the day, and I want to say it's math class. I didn't do my homework because I forgot, but then I notice something troubling because when I look down at my arms, there's two large holes in them. They're not bleeding, but they're like pretty deep pits, so I go to the nurse's office. When I arrive at the nurse's office, I kind of peek through the door that's opened up a little bit, and I see a man walking around. I don't want to disturb him, but also I need help. So eventually I knock on the door and go in and tell him that I need help with my arms. And then I wake up.
