Not sure anyone really knows – it may just be that our brain keeps ticking over while we are asleep or that it’s a way of our ‘subconscious’ making sense of everything that has gone on during the day.
I don’t think anyone really knows – your brain goes into a specific pattern when you sleep and dream (when they stick the electrodes on your head the pattern changes compared to when you’re awake) but we don’t know why. Good question!
Organising everything that’s happened to us that day, is what I had always thought. But to be honest I don’t know. Something to talk about at breakfast.
