I'm mostly interested in the idea of sleep. How much do we need it? Is it necessary? I'm a failure when it comes to pulling all nighters. I need my sleep even if it is at the cost of not getting my work done. How is it that some people can control this urge of falling asleep while I feel powerless towards it. What about dreams? I'm still not convinced in any concrete reason for why we dream. I feel like the dreams that I have that make sense to me, may mean something. But what about when I dream about things that don't have any meaning to me? Does this mean that they come from my unconscious? Does this mean they have more meaning that I give them credit for?
