Found herein are the various thoughts and random mental meanderings that, once removed from the to-and-fro of working memory (if you believe in such a cognitive beast), might clear out enough space to allow for sleep. There is nothing more descriptive to give in terms of content. It is whatever and wherever the brain bubbles happen to be.
BTW - the blog name comes from the book "Scepticism Inc." by Bo Fowler - an awesomely brilliant book that is sadly hard to find.
