Why do we dream?
Another thing that science hasn’t quite figured out is why we dream when we sleep. Obviously there are several theories as to why we might dream, but no clear-cut scientific reason yet.
To add to that, scientists don’t really know why we sleep either. Scientists know why sleep is important and how important it is to get enough of it, but they don’t know really why we do it when other species don’t require it as much.
There is never a time
