Question: how do you get nightmares?

Funny you should ask! I had a nightmare last night. It’s amazing how long after you finish having exams that you have nightmares about them. I still get nightmares about uni exams, but nothing about A-levels for a few years, thankfully.

Lots of students have asked about dreams so I have been looking into it. As far as I can tell there is no consensus about why we dream – it’s not know if it’s useful (e.g for processing memories) or just a side-effect of brain activity.

Nightmares are a type of dream so it looks like they’re not understood either.
