Dream Portal

The Dream Portal is a block which only can be placed above a Bed. If you interact with a bed with a Dream Portal above it, the screen will turn black and you will get two choices on where to go. Those places are The Shadow Realm and The Sweet Dream. Once you go to any of those places, the world will automatically save. A Dream Portal can be sold for 10.
