James Sully seems to be incorporating just about everyone we've studied, from a time long before they wrote.
He wants a neuroscientific way of explaining dreams, while also addressing them from a psychological perspective. He sees them as a way of getting at hidden feelings and, interestingly, even personalities.
He's furthest from Freud and rejects wish fulfillment in every dream although he sees some dreams as having an element of that. He is also suspicious of unchecked free association.
But unlike those we've studied, he also focuses on the actual pleasure of dreaming. He writes, "Whatever the moral dignity of these dream-disclosures may be, there is no doubt as to their having at their best a high hedonic and aesthetic value." Sully reminds us that dreams can be fun!
