What is the point of dreams if we do not remember them?

I draw your attention, here this Pigarev is smashed to smithereens, in his published article there were many verifiable factual errors, which suggests that it is not in vain that the visceral theory of sleep he proposed is still considered marginal. p>

Perhaps dreams have no meaning. See Ivan Pigarev's visceral sleep theory. In a nutshell, while you sleep, your brain is working on the problems of internal organs, and the more or less coherent pictures that you see in your sleep are something like a side effect.
