Why can't I ever remember my dreams?

Dreams are an important way the mind processes the activities of the day (or periods in between sleep, really) to de-clutter and re-energise for a whole new batch of random stuff to hit us with the new dawn.

They are a really clever idea of evolution (yes, I am definitely one of 'those' people who believe in science).

But to cut to the chase - I never remember my dreams. Never.

I'd appreciate any advice about fixing this - if you have any.

Thanks!!
