Strange Shelter (5e)

From the introduction: The heroes are in the middle of a long journey, passing through a semi-wilderness area. The area was controlled by goblinoids until recently, and some are said still to prowl the area. The characters take shelter from a storm in an abandoned farmhouse that is not what it seems. During the night, a ghost uses their dreams to take them back in time to the destruction of the farmhouse and the slaughter of its inhabitants to give the heroes a chance to prevent it. User summary: A mini-adventure for four or five 6th level characters.
