Your Brain Is Just As Busy When You Sleep As When You're Awake

Why do people sleep? — Well, not just people, but   all kinds of animals sleep. When you think about it, it’s actually quite  a strange idea that for ¼ to 1/3 of each day we go unconscious and   are oblivious to the world around us. Scientists for years have wondered  and studied what goes on when we sleep and why we do it.

Some of the best research happens through serendipity — Matthew Wilson was studying brain activity in rats as they run mazes.   One day he accidentally left the rats hooked up to the equipment he used  to record their brain activity. The rats eventually fell asleep, and to  Wilson’s surprise, he found that the brain activity while they were asleep was almost the same as the brain activity when the rats were   running the maze.

On the topic of dreams, is it common for alters to front in-dream? Is this their dreams or just the hosts? If an alter falls asleep would it be them dreaming? Sorry for all the questions >.<

I don’t know how common that is, but I’ve heard it discussed often enough to at least be able to say that it’s fairly normal! It may be that there’s been an actual switch, that the dream is showing a switch because it’s used to switching and so considers that a valid element to include, that the brain is showing one or more alters in the dream just as it would show outside people in the dream, or that the sleeping brain doesn’t maintain boundaries between alters well and so any alter could have the POV in a dream. The same system may even experience all  of these possibilities at different points in time while another system may have all dreams belong to the host because the host is the “default” state. Because of this, it’s difficult to say which alter may actually be dreaming (unless you’re using outside equipment to record your sleep patterns and know by now which patterns are associated with which alters; it has been done before!), but it doesn’t really matter in any case. It’s just kind of a cool thing to think about!
