His hand did in fact go up when Professor Euka asked who wanted a nap. She wasn't wrong that with a belly full of food, heading back to his dorm for a quick power nap would have been ideal. His hand went down as the discussion continued.

In truth, Evan didn't have any idea about dreams but he had already determined to try in this class so try he would. Better to be wrong than not offer an attempt at joining the discussion. So he raised his hand and waited for his turn. "Dreams are our subconscious continuing to work, even while we're asleep. I believe the brain can also sort them into short term and long term, like with most of our waking memories, so when you remember something it's long term. When you forget, it was filed short term and it might not be readily available when you're awake." Or was it the other way around?
