Recently, I had two dreams, and I've been trying to find the meaning of these dreams.

Dream 1: I was walking through my parents' house when I started throwing up blood. I don't mean coughing, and I don't really mean vomiting. It was like, every few steps I took, I would feel a large amount of blood come up, and I would spit it onto the floor. I would say about a cup's worth every time, maybe more. I moved toward the kitchen. I was afraid. My brother (who I have a pretty awful relationship with and have since I was a kid) came into the room. I slid down the wall and sat on the floor. I told him to call 911, but he just stood there. I screamed at him, "I'M VOMITING BLOOD! CALL 911, YOU IDIOT!" He walked away. I stopped being scared, and I was more angry that he didn't do anything, and I kept thinking about what an idiot he is. I stopped throwing up blood, and I just sort of sat there for a while, staring at the wall. I felt angry and sad. I didn't care that I was in a pool of my own blood. I didn't feel tired. It hadn't hurt to throw it up. I was just really sad. Angry. Sad. Mostly sad at that point. Then, I woke up. I can't really remember any other details. Oh, except that the kitchen table was gone.

Dream 2: Crab spiders. This pretty much sums up my dream. I was with my dad, and we were going to go out the backdoor. The entire backyard was crawling with crab spiders. This isn't really a thing. They don't exist (thankfully). They were literally crabs, with pinches and everything from the ocean, that were also spiders. So, they were spinning webs and stuff. One of them got into the house when I opened the door, and it kept spinning webs. My dad exited the dream at this point, and the crab spider that got inside kept chasing me. It was trying to get me, and I was terrified. I kept crying and screaming. It finally got me and kept pinching my hand. I had to pull it off, but it hurt so bad. I got it off my hand, and it pinched my foot. I got it off and threw it across the room. I was so terrified. I felt like it could kill me. My dad came back, and he was like, "Eh, it's just a crab spider." That's the entire dream, really. I woke up after that.

I've thought about what these dreams could mean, but I really don't know. Any help is much appreciated. Thank you for your time.
