Here we go:

• "Your brain recharges" is currently only one hypothesis about the function of sleep.

• "You can only dream about faces you've only seen". Can you? Or is this a case of you forcing recognition on to it in the same style that sometimes happens when trying to remember the perpetrator of a crime. I've heard this mentioned, but have thus far never seen any study backing it up. Nor can I even grasp the concept of a psychological experiment that can reasonably test this.

• "People who do not dream generally have personality disorders". What? Just, no. See various books and conference presentations referenced in http://www.ncbi.nlm.nih.gov/pubmed/9952252 - specifically schizotype, borderline and narcissistic.

• "Sleep positions may determine your personality". First of all, what's a sleeping position? Most people shift around in their sleep and most people I've slept with have multiple positions. Secondly, correlation does not imply causation. Thirdly, "personality"? They could at least have gone for a Meyers-Briggs personality typing, rather than these sorry excuses for personality.

• Discussing blind people "seeing" in dreams, specifically those who were born blind, is edging into the realms of philosophical discussion and whether we can truly know what someone else is experiencing and whether those experiences are the same as our own/universal.

• "50% of your dream...90% of your dream". I'd love to know how the hell this was quantified. Who even has a concept of time in a dream? If people are prone to forgetting dreams upon waking, how do you even know that you've remembered 100% at the moment precisely at waking (and therefore 50% later etc.). How does this take account of people, e.g. me, remembering dreams later in the day?

• "Sources". Yes, quite. I think "sauces" would be a better way to describe this.
