I rarely have nightmares and I tend not to have a lot of dreams on weeknights (I put my headphones on to help me wake up the next morning, which sort of interferes), but when I do, it's really stressful. It might be something like forgetting about a big test or school in general and just not doing what I'm supposed to. I know I'm meant to go to the school, so I end up going to the supermarket. By the time I'm there, I'm like, "Shouldn't I be at school?" so I end up doing the weekly shop.
There was one really horrible nightmare I had a few years ago. I was at school and there was some confusion about the tuck shop and a piece of cucumber, so my PE teacher made me swim up and down the pool on my back, just a few centimetres below the surface of the water, until the chlorine burned out my eyes. Oh, and my friends were thrown on a bonfire and I had to watch their skin burn off.
I used to have a lot of scary dreams where I was naked in public, but now that just acts as a trigger for lucid dreaming. It's like, "Ah! I'm naked! In public! But...that's not supposed to happen in real life. That must mean...I'm dreaming! HEY! Everyone! Look at me! I'm NEKKID!"
Nobody seems to care, so I just sit back and smile in the knowledge that I am, indeed, completely exposed.
Once, I woke up crying because my dad was going to steal this plant I picked in the garden.
