Interpret my Dream?

So last night I had a wierd a*s dream and it's kinda freaking me out.

So it starts out I'm with that guy hershel from the walking dead. Him and some kid are looking for weapons and I'm watching them and it was like the zombies were ignoring me. They were killing them and then the next thing I remember I'm in my backyard. That kid got killed by a zombie in my yard and some guy killed the zombie. I was walking into my house when I realized I had cancer. I had stage 3 cancer and didn't know what to do. I asked my mom for surgery and she said she'll think about it and I was very fatigued during the dream after I figured out I had cancer. So then I was texting this girl I had a crush on. ( literally 2 hours before I went to bed In real life I was texting her) and I don't say anything to her about cancer when I talked to her in my dream it was the total opposite of how we talk in real life. Then I go outside and that person that killed that zombie earlier was still out there. I straight up tell him that before the apocalypse I was depressed and thoughts of suicide. ( it's true in real life) and he didn't believe me and I walk out into the yard see the word neighbors painted on the side of my house and then I wake up. Can someone help me?
