Recurring dreams

This is a partial list of the dreams I have over and over again:

1. Zombie attack. I rarely have nightmares, but when I do they're either about this or trying to escape from an insane killer (I used to have nightmares about Jesus, but those don't happen anymore). One thing that always happens in my zombie dreams is I have to kill a zombie, or horde of zombies without the use of firearms. I have to bludgeon their skulls in, or cut their heads off, with whatever improvised item I find. And it always takes more than one swing to kill a zombie.

2. Back to school. Everybody pretty much gets this one. Where it's the end of the semester and you're in some class, and you realize you stopped going to this class after the first week or so, and you have no idea what's going on in it, and you're about to fail the final? What's unique about me is I've actually done this, several times. I had a Tuesday-Thursday English class that I could've passed in my sleep, except it was at 7 a.m. so I rarely if ever got up on time. Ever since I graduated, I've been dreaming that my diploma is actually invalid, because of this one class I failed to complete.

3. My brother pisses me off. And I always lose all my patience with him, and I try to punch him in the face, but my punches are weak and they rarely connect. It's like when you're trying to run in your dreams, but your feet have turned into lead. And yes, this is probably because I've done this in real life, too.

4. Stuck at church. In this one I'll be at my old church house, and I won't be able to leave for whatever reason. Sometimes I'm waiting for a ride, sometimes my parents are there and they have meetings. Most recently, I was playing basketball at church when a congregation suddenly came in and set up all the chairs for men to sit in and sing "My Girl" in a choir. After the song, I was waiting for them to clear the chairs so we could keep playing.

5. Eating/drinking something nasty Unlike the others, I actually know why I have this one. I breathe with my mouth open when I sleep, so it gets all dry in there and tastes like boiled ass. So when that happens and it's morning, I'll have dreams that I'm eating or drinking everything I can to get rid of the taste, and it doesn't work. Everything tastes like my mouth. Milkshakes, handfuls of bugs, KFC Famous Bowls, a cup full of wet cement, doesn't matter. The taste gets worse and worse until I wake up.

So, what do you think these mean? What scenes does your subconscious replay over and over again?
