Pillows, Dreams and How We’ve Changed

Would you believe, the use of pillows has altered how people dream?

The angle of the brain is different to when humans slept flat on the dirt. Blood flow is different. Connections within the brain are different — and that means different dreams.

And would you believe, sleeping without a pillow increases the “efficiency” of sleep and so less is needed.

*And if you believe any of this, you’re as insomniac’d as me 😉
