Dreams & Sleepers
Dreams are weird; I think we can all agree on that!
Scientists and philosophers argue over what dreams are, and if they have meaning or purpose... but sometimes dreams go a bit beyond just weird. Sometimes they appear to predict the future or reveal the past; or allow for communication that defies normal explanation; or make a sleeping person take actions that effect the non-sleeping world, sometimes in a deadly way.
So, yeah: Dreams are weird.
